Bill Haisten (June 2, 1995). "Chicago Cubs Fans Can Thank Tulsa's UVTV". Tulsa World. Retrieved April 29, 2019. (The article incorrectly states that WGN acquired rights to broadcast Chicago Cubs baseball games in 1980; until the team's local television rights became cable-exclusive after the 2019 Major League Baseball regular season ended, the Cubs were the only Chicago sports team to which WGN-TV had held uninterrupted rights, dating to its founding in 1948.)
