The decision to move most of the White Sox broadcasts to paid television led longtime announcer Harry Caray to become the play-by-play voice of the rival Chicago Cubs. He did this due to the limited exposure that the White Sox would experience as a result of having the majority of games on a medium that would limit the reach of the team's televised game broadcasts. Chicago was, until 2019, one of the very few television markets in the United States whose baseball teams made a substantial percentage of their games available over-the-air. Until the mid-1990s, the Cubs still televised all of their games that were not aired nationally on the major broadcast networks (ABC, NBC, CBS) over WGN-TV (channel 9), and a regional network of television stations throughout parts of the Midwest.
