NBC play-by-play man Bob Costas believed that a large bulk of the regular season coverage beginning in the 1990s shifted to cable (namely, ESPN) because CBS, the network that was taking over from NBC the television rights beginning in 1990, didn't really want the Saturday "Game of the Week". Many fans who didn't appreciate CBS' approach to scheduling regular season baseball games believed that they were only truly after the marquee events (i.e. All-Star Game, League Championship Series, and the World Series) in order to sell advertising space (especially the fall entertainment television schedule).
