One of the most influential behind-the-scenes figures in network television during the 1980s and 1990s, Warren Littlefield rose to prominence at NBC during its lengthy reign as the home of "Must See TV." As a young development executive, Littlefield was taken under the wing of NBC president Brandon Tartikoff in 1979. As Tartikoff's right-hand man, he helped revive the in-decline network with a string of hit comedies that began with the long-running "Cheers" (NBC, 1982-1993), soon to be followed by the likes of "The Cosby Show" (NBC, 1984-1992) and "The Golden Girls" (NBC, 1985-1992). One of Littlefield and Tartikoff's biggest risks also led to one of their greatest success stories - the rule-breaking sitcom "Seinfeld" (NBC, 1989-1998), a show "about nothing" that went on to be considered one of the greatest series of all time.
With the departure of his mentor, Littlefield stepped into his new role as NBC Entertainment President, and while sitcoms like "Mad About You" (NBC, 1992-99) were still on the menu, he placed increased focus on such dramatic fare as the career-launching medical drama "ER" (NBC, 1994-2009). Another breakout hit sitcom "Friends" (NBC, 1994-2004) and the progressive comedy "Will & Grace" (NBC, 1998-2006) rounded out the executive's impressive career at NBC prior to his stepping down in 1998. Unrecognized by the vast majority of TV viewers, during his heyday, Littlefield helped to shape the very landscape of television for nearly two decades.
