On July 8, 1999, WGN-TV and WCIU-TV entered into a programming arrangement involving sports coverage, which allowed channel 26 to carry select Chicago Bulls basketball and White Sox baseball games, and a handful of Cubs baseball games that are produced by and contracted to air on WGN-TV, due to that station's network affiliation contracts (with The CW and previously The WB) that limit the number of programming preemptions that WGN-TV is allowed on an annual basis, and rights restrictions enforced by the NBA which limited the number of Bulls telecasts aired on WGN's national superstation feed WGN America—prior to that channel's removal of WGN-produced programs upon its conversion into a basic cable channel in December 2014—to fifteen games per season.
