Bob Costas

On August 3, 2019, Costas alongside Paul O'Neill and David Cone called both games of a double-header between the New York Yankees and Boston Red Sox for the YES Network. Costas was filling in for Michael Kay, who was recovering from vocal cord surgery.

On January 15, 2019, it was announced that Costas had officially departed from NBC Sports after forty years.

Costas's final major on-air broadcast for NBC was hosting the 2018 Belmont Stakes, where Justify won the Triple Crown.

In November 2017, it was announced that Costas would alongside Krista Voda, co-anchor NBC's pre-race coverage leading into the NASCAR Cup Series finale from Homestead. In addition to hosting pre-race coverage, Costas would conduct a live interview with incoming NBC broadcaster Dale Earnhardt Jr., who was running his final race.

On February 9, 2017, Costas announced during Today that he had begun the process of stepping down from his main on-air roles at NBC Sports, announcing in particular that he would cede his role as primetime host for NBC's Olympics coverage to Mike Tirico (who joined the network from ESPN in 2016), and that he would host Super Bowl LII as his final Super Bowl. However, Costas ultimately dropped out of the coverage entirely.

While visiting the University of Maryland in November 2017 for a roundtable discussion on various sports topics, Costas said the sport of football was in a decline, with evidence mounting that the repetition of concussions "destroys people's brains" and he wouldn't allow a son with athletic talent to play it. Costas had been scheduled to work Super Bowl LII, his eighth as a host (despite stepping down from Football Night in America in favor of his successor Mike Tirico, Costas was to return while Tirico prepped to lead NBC's coverage of the 2018 Winter Olympics, set to begin a few days later). However, the network announced shortly before the game that Liam McHugh would instead join Dan Patrick as a co-host, leading to speculation that NBC removed Costas from the NFL's biggest game over his comments. Costas originally denied such, saying it made more sense for McHugh, who had been hosting Thursday night games on NBC, to serve in that capacity. However, he later admitted in an interview with ESPN's Outside the Lines that the comments were indeed the basis of his removal, ultimately resulting in his departure from the network after forty years.

On December 13, 2017, it was announced that Costas would receive the Ford C. Frick Award from the National Baseball Hall of Fame on July 28, 2018. In August 2018, the Sports Broadcasting Hall of Fame announced that Costas would be inducted to its body at a ceremony on December 11, 2018 honoring ten other sports figures including Dick Vitale, Jim Nantz and Bud Greenspan.

Costas appeared on the September 22, 2017 episode of Real Time with Bill Maher to discuss issues such as concussions and the role of political activism in professional sports (namely by Colin Kaepernick).

USA Today reported that he would similarly step down from Football Night in America in favor of Tirico. Costas explained that he was not outright retiring and expected to take on a role at NBC Sports similar to that of Tom Brokaw, being an occasional special correspondent to the division. He explained that his decision "opens up more time to do the things that I feel I'm most connected to; there will still be events, features, and interviews where I can make a significant contribution at NBC, but it will also leave more time for baseball (on MLB Network), and then, at some point down the road, I'll have a chance to do more of the long-form programming I enjoy." Costas told USA Today his gradual retirement was planned in advance, and that he did not want to announce it during the 2016 Summer Olympics or the NFL season because it would be too disruptive, and joked: "I'm glad that Sochi wasn't the last one. You wouldn't want your pink-eye Olympics to be your last Olympics."

As aforementioned, Costas hosted Thursday Night Football on NBC and NFL Network in 2016, having returned to broadcasting after a brief absence. He was replaced by Liam McHugh in 2017.

On March 30, 2015, it was announced that Costas would join forces with Marv Albert (blow-by-blow) and Al Michaels (host) on the April 11, 2015, edition of NBC's primetime PBC on NBC boxing series. Costas was added to serve as a special contributor for the event from Barclays Center in Brooklyn. He would narrate and write a feature on the storied history of boxing in New York City.

Following the Olympics, Costas appeared on Conan O'Brien's talk show and jokingly criticized his employer for its decision to air a preview of the upcoming series Animal Practice over a performance by The Who during the London closing ceremonies. "So here is the balance NBC has to consider: The Who, 'Animal Practice'. Roger Daltrey, Pete Townshend—monkey in a lab coat. I'm sure you'd be the first to attest, Conan, that when it comes to the tough calls, NBC usually gets 'em right," Costas said, alluding at the end to O'Brien's involvement in the 2010 Tonight Show conflict.

An eye infection Costas had at the start of the 2014 Winter Olympics forced him, on February 11, 2014, to cede his Olympic hosting duties to Matt Lauer (four nights) and Meredith Vieira (two nights), the first time Costas had not done so at all since the 1998 Winter Olympics (as rights were not held by NBC).

September 25, 2014: Costas called Derek Jeter's final game at Yankee Stadium for MLB Network, where he hit an RBI single to win the game. Costas's call:

During his coverage of the 2014 Winter Olympics, Costas was criticized by some conservative members of the media, including Michelle Malkin and Glenn Beck for supposedly praising Vladimir Putin's role in defusing tensions surrounding Syria, and Iran. Several media commentators, including Bill O'Reilly and Bernard Goldberg, defended Costas' remarks as factually correct and pointed out that Costas had also voiced considerable criticism of both Russia and Putin while broadcasting from Sochi. During an interview on Fox News Goldberg said "...  the idea that Costas somehow portrayed Vladimir Putin as a benign figure is ridiculous." Costas defended himself on O'Reilly's broadcast on March 3, reiterating that he criticized Putin immediately preceding, and following, the statements that were questioned. O'Reilly then aired a portion of an Olympic commentary in which Costas was pointedly critical of the Russian leader. Costas also indicated that Senator John McCain, who had been among those who had initially criticized Costas, had called Costas to apologize after hearing the full segment in context.

Costas: 1–1 pitch. [Sandberg swings] Kubek: OHHH BOY! Costas: [Over Kubek] And he hits it to deep left center! Look out! Do you believe it, it's gone! We will go to the 11th, tied at 11.

The 0–1 pitch. A liner  ... off Nagy's glove, into center field. The Florida Marlins have won  ... the World Series.

In June 2013, Costas provided the voice of God in the Monty Python musical Spamalot at The Muny Repertory in St. Louis.

In January 2013, Costas appeared as himself in the Go On episode "Win at All Costas" with Matthew Perry, wherein Ryan King auditions with him for a TV Show.

Along with co-host Meredith Vieira and Matt Lauer, Costas' commentary of the 2012 Summer Olympics Opening Ceremonies came under fierce criticism, with Costas being described as making "a series of jingoistic remarks, including a joke about Idi Amin when Uganda's team appeared" and the combined commentary as being "ignorant" and "banal".

During a segment on the Sunday Night Football halftime show on December 2, 2012, Costas paraphrased Fox Sports columnist Jason Whitlock in regard to Jovan Belcher's murder-suicide the day prior, saying the United States' gun culture was causing more domestic disputes to result in death, and that it was likely Belcher and his girlfriend would not have died had he not possessed a gun.

Costas's children have also won Sports Emmys; Keith has won two as an associate producer on MLB Network's MLB Tonight, and Taylor as an associate producer on NBC's coverage of the 2012 Summer Olympics.

Costas has won eight National Sportcaster of the Year awards from the National Sportscasters and Sportswriters Association. He was inducted into that organization's Hall of Fame in 2012. He has also won four Sportscaster of the Year awards from the American Sportscasters Association and well over twenty Sports Emmy Awards for announcing. He is the only person in television history to have won Emmys for Sports, News (Sandusky interview), and Entertainment (Later).

Beginning in October 2011, Costas was a correspondent for Rock Center with Brian Williams. He gained acclaim for his November 2011 live interview of former Pennsylvania State University assistant coach Jerry Sandusky concerning charges of sexual abuse of minors, in which Sandusky called in to deny the charges.

Costas' voice appeared in the 2011 documentary film Legendary: When Baseball Came to the Bluegrass, which detailed the humble beginnings of the Lexington Legends, a minor league baseball team located in Lexington, Kentucky.

Costas provided significant contributions to the Ken Burns, PBS mini series Baseball as well as its follow-up The 10th Inning. He also appears in another PBS film, A Time for Champions, produced by St. Louis's Nine Network of Public Media.

Costas guest-voiced as himself in 2010 Simpsons episode, "Boy Meets Curl", when Homer and Marge make the U.S. Olympic curling team. Costas also guest-voiced as himself on the Family Guy episode "Turban Cowboy" in an interview with Peter after he wins the Boston Marathon by hitting everyone with his car.

On February 11, 2010, Stephen Colbert jokingly expressed his desire to stab Costas with an ice pick at the upcoming 2010 Winter Olympics in Vancouver so Colbert could take over as host. Costas later made a cameo appearance on the February 25, 2010, edition of Colbert's show.

Costas hosted the syndicated radio program Costas Coast to Coast from 1986 to 1996, which was revived as Costas on the Radio. Costas on the Radio, which ended its three-year run on May 31, 2009, aired on 200 stations nationwide each weekend and syndicated by the Clear Channel owned Premiere Radio Networks. During that period, Costas also served as the imaging voice of Clear Channel-owned KLOU in St. Louis, Missouri, during that station's period as "My 103.3". Like Later, Costas' radio shows have focused on a wide variety of topics and have not been limited to sports discussion.

Costas left HBO to sign with MLB Network in February 2009.

At the channel's launch on January 1, 2009, Costas hosted the premiere episode of All Time Games, a presentation of the recently discovered kinescope of Game  5 of the 1956 World Series. During the episode, he held a forum with Don Larsen, who pitched MLB's only postseason perfect game during that game, and Yogi Berra, who caught the game.

Costas joined the network full-time on February 3, 2009. He hosts a regular interview show titled MLB Network Studio 42 with Bob Costas as well as special programming and provides play-by-play for select live baseball game telecasts. In 2017, Costas called Game  1 of the American League Division Series between the Boston Red Sox and the Houston Astros on MLB Network. The Astros went on to win 8–2. Unfortunately, Costas and his color commentator Jim Kaat received criticism for their "bantering about minutia" and misidentification of plays. Costas also went on to become an internet meme after using the term the "sacks were juiced" to describe the bases being loaded.

On January 30, 2009, Costas guest-starred as himself on the television series Monk in an episode titled "Mr. Monk Makes the Playoffs"'. He mentions to Captain Stottlemeyer about how Adrian Monk once helped him out of a problem several years ago with regards to a demented cat salesman. He apparently sold Costas a cat that allegedly tried to kill him with a squeeze toy. (In fact when he signs off he says, "The cat was definitely trying to kill me.")

Costas hosted NBC's coverage of the 2008, 2009, and the 2010 NHL Winter Classic. He was scheduled to host coverage of the 2011 event as well but, due to the game's postponement, Costas hosted only pre-game coverage before leaving to go to Seattle for his duties with NBC's NFL coverage the next night. He hosted the event in 2012 as well as a post-game edition of NHL Live on the NBC Sports Network.

On June 13, 2008, Costas appeared on MSNBC's commercial-free special coverage of Remembering Tim Russert (1950–2008).

On May 26, 2007, Costas discussed the presidency of George W. Bush on his radio show, stating he liked Bush personally, and had been optimistic about his presidency, but said the course of the Iraq war, and other mis-steps have led him to conclude Bush's presidency had "tragically failed" and considered it "overwhelmingly evident, even if you're a conservative Republican, if you're honest about it, this is a failed administration." The following summer, Costas interviewed Bush during the president's appearance at the 2008 Summer Olympics in Beijing.

In 2006, Costas returned to NFL studio hosting duties for NBC's new Sunday Night Football, hosting its pre-game show Football Night in America. Costas last hosted NFL telecasts for NBC in 1992 before being replaced in the studio by Jim Lampley and subsequently, Greg Gumbel. Before becoming the studio host for The NFL on NBC in 1984, Costas did play-by-play of NFL games with analyst Bob Trumpy.

Costas is nicknamed "Rapping Roberto" by New York City's Daily News sports media columnist Bob Raissman. Al Michaels also called him "Rapping Roberto" during the telecast between the Indianapolis Colts and the New York Giants on September 10, 2006, in response to Costas calling him "Alfalfa".

In June 2005, Costas was named by CNN president Jonathan Klein as a regular substitute anchor for Larry King's Larry King Live for one year. Costas, as well as Klein, have said Costas was not trying out for King's position on a permanent basis. Nancy Grace was also named a regular substitute host for the show. On August 18, 2005, Costas refused to host a Larry King Live broadcast where the subject was missing teenager Natalee Holloway. Costas said that because there were no new developments in the story, he felt it had no news value, and he was uncomfortable with television's drift in the direction of tabloid-type stories.

On March 12, 2004, Costas married his second wife, Jill Sutton. Costas and his wife now reside primarily in New York, but he has often said he thinks of St. Louis as his hometown.

Costas has also hosted NBC's coverage of the U.S. Open golf tournament from 2003 to 2014.

In 2002, Costas began a stint as co-host of HBO's long-running series Inside the NFL. Costas remained host of Inside the NFL through the end of the 2007 NFL season. He hosted the show with Cris Collinsworth and former NFL legends Dan Marino and Cris Carter. The program aired each week during the NFL season.

In 2002, Costas was the play-by-play announcer, alongside Harold Reynolds, for Triple Play 2002 during the ballgame for PlayStation 2 and Xbox.

From 2001 until 2018, Costas co-hosted the Kentucky Derby. In 2009, he hosted Bravo's coverage of the 2009 Kentucky Oaks. After Costas officially departed from NBC Sports, his role on NBC's thoroughbred racing coverage was essentially filled-in by Rebecca Lowe, beginning with the 2019 Kentucky Derby.

In 2001, Costas was hired by HBO to host a 12-week series called On the Record with Bob Costas. On the Record with Bob Costas was similar to the format of the old Later program as they both concentrated on in-depth interviews. In 2005, On the Record with Bob Costas was revamped to become Costas Now, a monthly issue oriented sports program that occasionally employed a town hall style format.

June 4, 2000: Costas called Game 7 of the 2000 Western Conference Finals for NBC's NBA coverage. Kobe Bryant threw an alley oop pass to Shaquille O'Neal to give the Lakers a six-point lead with 41.3 seconds remaining. Costas's call of the play:

Costas is a devoted baseball fan. He's been suggested as a potential commissioner and wrote Fair Ball: A Fan's Case for Baseball in 2000. For his 40th birthday, then Oakland Athletics manager Tony La Russa allowed Costas to manage the club during a spring training game. The first time Costas visited baseball legend Stan Musial's St. Louis eatery, he left a $3.31 tip on a ten dollar tab in homage to Musial's lifetime batting average (.331). Costas delivered the eulogy at Mickey Mantle's funeral. In eulogizing Mantle, Costas described the baseball legend as "a fragile hero to whom we had an emotional attachment so strong and lasting that it defied logic". Costas has even carried a 1958 Mickey Mantle baseball card in his wallet. Costas also delivered the eulogy for Musial after his death in early 2013.

In 1999, Costas teamed with his then-NBC colleague Joe Morgan to call two weekday night telecasts for ESPN. The first was on Wednesday, August 25 with Detroit Tigers playing against the Seattle Mariners. The second was on Tuesday, September 21 with the Atlanta Braves playing against the New York Mets.

June 14, 1998: Costas called Game 6 of the 1998 NBA Finals, Michael Jordan and Phil Jackson's final game with the Chicago Bulls where Jordan hit a 20 foot jumpshot to put the Bulls up 87–86 with 5.2 seconds remaining. The Bulls would win the game by that score, giving them their sixth championship and third consecutive. Costas's call:

October 26, 1997: Costas called Game 7 of the 1997 World Series, where Édgar Rentería hit a walk off single to give the Marlins their first World Series championship. Costas's call:

Costas decided to leave Later after six seasons, having grown tired of the commute to New York City from his home in St. Louis and wishing to lighten his workload in order to spend more time with his family. He also turned down an offer from David Letterman, who moved to CBS in 1995, to follow him there and become the first host of The Late Late Show, which was being developed by Letterman's company to air at 12:30 after the Late Show with David Letterman.

In 1995, Costas received a star on the St. Louis Walk of Fame. In 1999, he was a recipient of the Curt Gowdy Media Award from the Basketball Hall of Fame, which is awarded to members of the electronic and print media for outstanding contributions to the sport. In 2000, he won a TV Guide Award for Favorite Sportscaster. In 2001, Syracuse University honored Costas with the George Arents Award, SU's highest alumni honor, for Excellence in Sports Broadcasting. He was selected as the Dick Schaap Award for Outstanding Journalism recipient in 2004. In 2006, he was also awarded an honorary doctorate in humane letters from Loyola College in Maryland. In 2012, Costas was awarded the Walter Cronkite Award for Excellence in Journalism. In 2013, the S.I. Newhouse School of Public Communications honored him with the first Marty Glickman Award for Leadership in Sports Media.

In 1994, Costas appeared as the play-by-play announcer for the World Series (working alongside Tim McCarver) in the movie The Scout. In 1998, he appeared as himself along with his rival/counterpart Al Michaels (who now works for NBC) from ABC in the movie BASEketball. Costas voiced an animated car version of himself, Bob Cutlass, in the movies Cars (2006) and Cars 3 (2017). He also appeared as himself in the 2001 movie Pootie Tang, where he remarks that he saw "the longest damn clip ever".

Real footage of Costas from NBC's pregame show before Game  5 of the 1994 NBA Finals was used in the second episode of The People v. O.J. Simpson: American Crime Story.

In 1993, Costas hosted the "pregame" show for the final episode of Cheers. Costas once appeared on the television program NewsRadio as himself. He hosted an award show and later had some humorous encounters with the crew of WNYX. Costas also once appeared as a guest on the faux talk show cartoon Space Ghost Coast to Coast.

During the 1992 Barcelona and 1996 Atlanta Opening Ceremonies, Costas's remarks on China's teams' possible drug use caused an uproar among the American Chinese and international communities. Thousands of dollars were raised to purchase ads in The Washington Post and Sunday The New York Times, featuring an image of the head of a statue of Apollo and reading: "Costas Poisoned Olympic Spirit, Public Protests NBC". However, Costas' comments were made subsequent to the suspension of Chinese coach Zhou Ming after seven of his swimmers were caught using steroids in 1994. Further evidence of Chinese athletes' drug use came in 1997 when Australian authorities confiscated 13 vials of Somatropin, a human growth hormone, from the bag of Chinese swimmer Yuan Yuan upon her arrival for the 1997 World Swimming Championships. At the World Championships, four Chinese swimmers tested positive for the banned substance Triamterene, a diuretic used to dilute urine samples to mask the presence of anabolic steroids. Including these failed drug tests, 27 Chinese swimmers were caught using performance-enhancing drugs from 1990 through 1997; more than the rest of the world combined.

When NBC gained the NBA network contract from CBS in 1990, Costas hosted the telecasts and was teamed in the studio with ex-Lakers coach Pat Riley. He also hosted the studio program Showtime and did play-by-play for the 1991 All-Star Game. In 1997, Costas began a three-year stint as the lead play-by-play man for The NBA on NBC. NBC enlisted Costas' services after they were forced to (temporarily) remove Marv Albert from their broadcasts due to lingering personal and legal problems at the time. Costas teamed with Isiah Thomas and Doug Collins for NBA telecasts from 1997 to 2000. He stepped aside following the 2000 NBA Finals in favor of a returning Albert. While this, in essence, ended his active role on the NBA on NBC program (by this point, Hannah Storm and briefly, Ahmad Rashād had replaced Costas on studio anchoring duties), Costas would return to do play-by-play for selected playoff games. He returned to call some games of the 2002 NBA Playoffs after Albert was injured in a car accident two days before the playoffs. Costas also co-anchored (with Hannah Storm) NBC's NBA Finals coverage in 2002, which was their last to-date (before the NBA's network television contract moved to ABC).

Besides calling the 1989 American League Championship Series for NBC, Costas also filled in for a suddenly ill Vin Scully, who had come down with laryngitis, for Game  2 of the 1989 National League Championship Series alongside Tom Seaver. Game  2 of the NLCS took place on Thursday, October 5, which was an off day for the ALCS. NBC then decided to fly Costas from Toronto to Chicago to substitute for Scully on Thursday night. Afterward, Costas flew back to Toronto, where he resumed work on the ALCS the next night.

While hosting Game 4 of the 1988 World Series between the Los Angeles Dodgers and Oakland Athletics on NBC, Costas angered many members of the Dodgers (especially the team's manager, Tommy Lasorda) by commenting before the start of the game that the Dodgers quite possibly were about to put up the weakest-hitting lineup in World Series history. That comment ironically fired up the Dodgers' competitive spirit. Later (while being interviewed by NBC's Marv Albert), after the Dodgers had won Game  4 (en route to a 4–1 series victory), Lasorda sarcastically suggested the MVP of the 1988 World Series should be Bob Costas.

Costas has frontlined many Olympics broadcasts for NBC. They include the 1988 Winter Olympics in Calgary and 1988 Summer Olympics in Seoul, Barcelona in 1992, Atlanta in 1996, Sydney in 2000, Salt Lake City in 2002, Athens in 2004, Torino in 2006, Beijing in 2008, Vancouver in 2010, London in 2012, Sochi in 2014 and Rio in 2016. He discusses his work on the Olympic telecasts extensively in a book by Andrew Billings entitled Olympic Media: Inside the Biggest Show on Television. A personal influence on Costas has been legendary ABC Sports broadcaster Jim McKay, who hosted many Olympics for ABC from the 1960s to the 1980s.

Costas hosted Later with Bob Costas on NBC from 1988 until 1994. This late night show created by Dick Ebersol, coming on at 1:30 a.m. as the third program in NBC's nightly lineup after The Tonight Show Starring Johnny Carson and Late Night with David Letterman, was something of a break from the typical TV talk show format of the era, featuring Costas and a single guest conversing for the entire half hour, without a band, opening monologue or studio audience. On several occasions, Costas held the guest over for multiple nights. The show was taped in GE Building's studios 3B or 8H at the Rockefeller Plaza, with Costas interviewing the guest for 45 minutes to an hour before turning the material over to editors who condensed it down to 22 minutes plus commercial breaks. More popular guests were given two- or three-part interviews; in August 1991 Mel Brooks was the only guest on four consecutive nights. The program was critically acclaimed and twice nominated for Emmys during its ​5  ⁄2 -year run, winning the Emmy for Best Informational Series in 1993.

In 1985, Costas appeared on The War to Settle the Score, a pre-WrestleMania program that the World Wrestling Federation aired on MTV.

For baseball telecasts, Costas teamed with Sal Bando (1982), Tony Kubek (from 1983 to 1989), and Joe Morgan and Bob Uecker (from 1994 to 2000). One of his most memorable broadcasts occurred on June 23, 1984 (in what would go down in baseball lore as "The Sandberg Game"). Costas, along with Tony Kubek, was calling the Saturday baseball Game of the Week from Chicago's Wrigley Field. The game between the Chicago Cubs and St. Louis Cardinals in particular was cited for putting Ryne Sandberg (as well as the 1984 Cubs in general, who would go on to make their first postseason appearance since 1945) "on the map". In the ninth inning, the Cubs, trailing 9–8, faced the premier relief pitcher of the time, Bruce Sutter. Sandberg, then not known for his power, slugged a home run to left field against the Cardinals' ace closer. Despite this dramatic act, the Cardinals scored two runs in the top of the tenth. Sandberg came up again in the tenth inning, facing a determined Sutter with one man on base. Sandberg then shocked the national audience by hitting a second home run, even farther into the left field bleachers, to tie the game again. The Cubs went on to win in the 11th inning. When Sandberg hit that second home run, Costas said, "Do you believe it?!" The Cardinals' Willie McGee also hit for the cycle in the same game.

June 23, 1984: Costas called NBC's Game of the Week with Tony Kubek, where Ryne Sandberg hit two separate home runs in the 9th and 10th innings against Bruce Sutter to tie the game. This game is known as "The Sandberg Game".

Costas was married from 1983 to 2001 to Carole "Randy" Randall Krummenacher. They had two children, son Keith (born 1986) and daughter Taylor (born 1989). Costas once jokingly promised Minnesota Twins center fielder Kirby Puckett that, if he was batting over .350 by the time his child was born, he would name the baby Kirby. Kirby was hitting better than .350, but Bob's son initially was not given a first (or second) name of Kirby. After Puckett reminded Costas of the agreement, the birth certificate was changed to "Keith Michael Kirby Costas".

In 1980, Costas was hired by NBC. Don Ohlmeyer, who at the time ran the network's sports division, told 28-year-old Costas he looked like a 14-year-old. Costas would recite this anecdote during an appearance on Late Night with Conan O'Brien. Ohlmeyer based his reaction on Costas' modest stature (Costas is 5 ft 7 in (1.70 m)) and boyish, baby-faced appearance.

Costas anchored NBC's pre- and post-game shows for NFL broadcasts and the pre and post-game shows for numerous World Series and Major League Baseball All-Star Games during the 1980s (the first being for the 1982 World Series). Costas did not get a shot at doing play-by-play (as the games on NBC were previously called by Vin Scully) for an All-Star Game until 1994 and a World Series until 1995 (when NBC split the coverage with ABC under "The Baseball Network" umbrella), when NBC regained Major League Baseball rights after a four-year hiatus (when the broadcast network television contract moved over to CBS, exclusively). It was not until 1997 when Costas finally got to do play-by-play for a World Series from start to finish. Costas ended up winning a Sports Emmy Award for Outstanding Sports Personality, Play-by-Play.

Later, Costas would call Missouri Tigers basketball and co-host KMOX's Open Line call-in program. He did play-by-play for Chicago Bulls broadcasts on WGN-TV during the 1979–1980 NBA season. From 1978 to 1981, Costas worked as a fill-in play-by-play man on St. Louis Blues radio broadcasts on KMOX whenever the regular play-by-play announcer, Dan Kelly, was unavailable. He was also employed by CBS Sports as a regional CBS NFL and CBS NBA announcer from 1976 to 1979, after which he moved to NBC.

Costas was born in Queens, New York City, and grew up in Commack, New York. He is the son of Jayne (Quinlan), of Irish descent, and John George Costas, an electrical engineer of Greek descent. His father's ancestry can be traced back to the island of Kalymnos in the Aegean Sea in Greece. As Costas stated on Ken Burns' Baseball, he had a very poor relationship with his father. Costas graduated from Commack High School South and attended Syracuse University in Syracuse, New York. He graduated with a communications degree in 1974 from their S.I. Newhouse School of Public Communications.

After graduating in 1974 at the age of 22, Costas went to KMOX radio in St. Louis, Missouri, calling play-by-play for the Spirits of St. Louis of the American Basketball Association in 1974. He was a prominent contributor to the ABA book Loose Balls: The Short, Wild Life of the American Basketball Association. He is extensively quoted on many topics. The book includes his reflections of ABA life during his tenure as radio voice of the Spirits of St. Louis.

In 1973, Costas began his professional career at WSYR TV and radio in Syracuse while still completing his communications degree at the S.I. Newhouse School of Public Communications. His sportscasting career began while attending Syracuse University, serving as an announcer for the Syracuse Blazers minor-league hockey team playing in the Eastern Hockey League and North American Hockey League.

Robert Quinlan Costas (born March 22, 1952) is an American sportscaster who is employed by MLB Network, where he does play-by-play and hosts an interview show called Studio 42 with Bob Costas. He is known for his long tenure with NBC Sports, from 1980 through 2019. He has received several Emmy awards for his work. He was the prime-time host of 11 Olympic Games from 1992 until 2016.
