In 1950, the NCAA moved the College World Series (CWS) to Rosenblatt Stadium, (then known as Omaha Municipal Stadium). Started in 1947, the tournament was held at Kalamazoo, Michigan in 1947 and 1948, and Wichita, Kansas in 1949. Since 1950 the series has been held annually at the Rosenblatt, despite bids from several cities to move the CWS to another venue. More than 6,000,000 fans have attended CWS games in Omaha. The City of Omaha has regularly expanded and renovated the stadium to accommodate fans, teams, and media covering the event. ESPN televised every game of the event from 1980 through 1987. ESPN started coverage again when the championship series went to a best-of-3 format in 2003. From 1988 through 2002, CBS televised the championship game: a winner-take-all single game.
