USA - Keith Olbermann

Keith Olbermann may be best known for anchoring ESPN's "SportsCenter" from 1992 to 1997, when his inimitable style made the blend of pop culture and sports a hallmark of the modern television sports reporter. While at ESPN, Olbermann helped launch ESPN2 and ESPN Radio network, and wrote the critically acclaimed book "The Big Show" about his experiences working on "SportsCenter." Olbermann began his career with NBC in 1997, when he was anchor for NBC Sports, hosting the World Series and Major League Baseball's All-Star Game, and contributing to pre-game coverage of the Super Bowl. During that time he was also host of two primetime news programs on MSNBC, "The Big Show," and "White House In Crisis." Olbermann returned to MSNBC in 2003 as a substitute host on "Nachman" and an anchor for MSNBC's coverage of the war in Iraq before launching "Countdown" in 2003.
