Jeff Zucker

Dowd also reported that an unnamed "honcho at another network" stated that "Zucker is a case study in the most destructive media executive ever to exist... You’d have to tell me who else has taken a once-great network and literally destroyed it."

In March 2019, CNN parent WarnerMedia announced a reorganization in which Zucker would become chairman of the company's news and sports division, overseeing Turner Sports, Bleacher Report and AT&T SportsNet, in addition to maintaining his role as head of CNN.

During the 2016 presidential election campaign, a large focus was placed upon on-air debates between partisan pundits surrounding issues relating to the candidates (including, in particular, Republican candidate Donald Trump). In an interview with The New York Times, Zucker stated that aspects of its election coverage were influenced by sports channels (with the Times citing, specifically, debates between pundits reminiscent of shows such as ESPN's First Take, and large outdoor "pre-game" shows for the presidential debates), explaining that "the idea that politics is sport is undeniable, and we understood that and approached it that way." In 2016, CNN reached a monthly average of 105 million unique visitors to its web and mobile properties.

With the 2014 cancellation of Piers Morgan Live, CNN experimented with airing factual programming in primetime as an alternative, with Zucker stating that it would cater to younger demographics than pundit-oriented programs. However, Zucker still insisted that news remained CNN's first priority, and that these programs could be preempted for continuing coverage of breaking news events when needed. 2014 saw an increase in daytime and primetime viewership of CNN; by October 2014, CNN had overtaken MSNBC in primetime key demographic viewership, placing second behind Fox News Channel.

Zucker became president of CNN Worldwide on January 1, 2013. His appointment was widely welcomed by the network and its anchors. Anderson Cooper told colleagues that Zucker was "the first CNN president to actually watch CNN". In December 2013, Zucker stated that his goal for the channel was to offer an "attitude and a take" to viewers, with a larger focus on reality-style documentary series (expanding upon the success of its documentary acquisition Blackfish, and new series Anthony Bourdain: Parts Unknown). Zucker explained that he wanted CNN to appeal more to regular viewers of factual networks (such as A&E, Discovery, and History), and make larger investments into the network's digital properties.

In 2010, in response to a public controversy over the network's reported rescheduling of late-night hosts Jay Leno and Conan O'Brien, Los Angeles Times reporters Meg James and Matea Gold wrote that Zucker's tenure had led to "a spectacular fall by the country's premier television network" and dubbed the intra-network feud and subsequent public relations fallout "one of the biggest debacles in television history". Under Zucker NBC fell from being the number one rated network to the lowest rated of the four broadcast networks and was occasionally being beaten in the ratings by programming on some of the more popular cable channels.

On June 2, 2010, the New York Post reported that Zucker would be paid between $30 million and $40 million to leave NBC Universal shortly after Comcast completed its 51% acquisition in the company.

On February 6, 2007, Zucker became president and CEO of NBC Universal.

On December 15, 2005, Zucker was promoted by NBC to Chief Executive Officer of NBC Universal Television Group behind Robert Charles Wright, vice chairman of General Electric and chairman & CEO of NBC Universal. Zucker was responsible for all programming across the company’s television properties, including network, news, cable, sports and Olympics. His responsibilities also included the company’s studio operations and global distribution efforts.

Following the merger with French media empire Vivendi Universal, he became president of its Television Group in May 2004. During Zucker's tenure, shows that he championed such as Father of the Pride and the Friends spinoff Joey were considered failures.

In December 2003, Zucker became president of NBC's Entertainment, News & Cable Group as well.

In 2000, he was named NBC Entertainment's president. A 2004 Businessweek Profile stated that "During that time he oversaw NBC's entire entertainment schedule. He kept the network ahead of the pack by airing the gross out show Fear Factor, negotiating for the cast of the hit series Friends to take the series up to a tenth season, and signing Donald Trump for the reality show The Apprentice. He is credited with the idea to extend Friends episodes by 10 minutes and convinced the cast to extend their contracts by two years. The Friends era was one of the most profitable ever for NBC. The Zucker era produced a spike in operating earnings for NBC, from $532 million the year he took over to $870 million in 2003."

In 1996, Zucker married Caryn Stephanie Nathanson, then a supervisor for Saturday Night Live, with whom he has four children. Diagnosed at ages 31 and 34 with colon cancer, Zucker successfully underwent surgery twice and chemotherapy after the first surgery. In July 2018, Zucker had to move away from CNN's leadership to recover from heart surgery.

In 1989, he was a field producer for Today, and at 26 he became its executive producer in 1992. He introduced the program's trademark outdoor rock concert series and was in charge as Today moved to the "window on the world" Studio 1A in Rockefeller Plaza in 1994. He is credited with managing the show during its most successful years and launching it into its 16-years of ratings dominance.

When he was not admitted to Harvard Law School, he took a job at NBC in 1986 to research information for its coverage of the 1988 Summer Olympics.

He was a captain of the North Miami Senior High School tennis team, editor of the school paper, and a teenage freelance reporter ("stringer") for The Miami Herald. Zucker also was president of his sophomore, junior, and senior classes, running on the slogan "The little man with the big ideas." He graduated from North Miami Senior High School in 1982. Before college, he took part in Northwestern University's National High School Institute program for journalism. Zucker went on to Harvard University. He was president of the school newspaper, The Harvard Crimson, during his senior year and as such he encouraged the decades-old prank rivalry with the Harvard Lampoon, headed by future NBC colleague Conan O'Brien. Zucker graduated from Harvard in 1986 with a Bachelor of Arts in American history.

Jeffrey Adam Zucker (born April 9, 1965) is an American media executive. He previously served as president and CEO of NBCUniversal.

Zucker oversees CNN, CNN International, HLN, and CNN Digital.

Zucker was born into a Jewish family in Homestead, Florida, near Miami, on April 9, 1965. His father, Matthew, was a cardiologist, and his mother, Arline, was a school teacher.
