200: Number of countries where CNN is available

Why he matters: With a little more than a year under his belt at CNN, Zucker -- the former CEO of NBCUniversal -- has launched seven new programs comprising 25 hours a week and broadened the network's programming with documentary acquisitions, including the Oscar-nominated Blackfish, and series fronted by well-known unscripted stars, including Anthony Bourdain and Morgan Spurlock. Bourdain's show, Parts Unknown, garnered CNN its first primetime Emmys last year and now is the network's most-watched program. At the same time, CNN Films has become a player on the film festival circuit, snapping up docs from such A-listers as Alex Gibney, Robert Redford, Tom Hanks and Gary Goetzman. If many of Zucker's programs, including morning show New Day, are also-rans behind top-rated Fox News and MSNBC, CNN's nonpartisan brand still plays well with advertisers (and viewers) not looking to choose political sides. Zucker, 49, a married father of four, also recently declared that the primetime interview show, epitomized by former CNN mainstay Larry King, is dead. All eyes are on the net's new nightly lineup, which will have original series and documentaries at 9 p.m., to see if the former Today executive producer still has that producer's gut.

Goal for next year: "To truly go there [the network's new tagline] with our new brand and continue to improve our primetime performance."

Proudest accomplishment this year: "Making CNN more relevant."
