TBN meaning in Sports ?

The Baseball Network was a short-lived television broadcasting joint venture between ABC, NBC and Major League Baseball. Under the arrangement, beginning in the 1994 season, the league produced its own in-house telecasts of games, which were then brokered to air on ABC and NBC. This was perhaps most evident by the copyright beds shown at the end of the telecasts, which stated "The proceeding program has been paid for by the office of The Commissioner of Baseball". The Baseball Network was the first television network in the United States to be owned by a professional sports league. In essence, The Baseball Network could be seen as a forerunner to the MLB Network, which would debut about 15 years later.

The package included coverage of games in prime time on selected nights throughout the regular season (under the branding Baseball Night in America), along with coverage of the postseason and the World Series. Unlike previous broadcasting arrangements with the league, there was no national "game of the week" during the regular season; these would be replaced by multiple weekly regional telecasts on certain nights of the week. Additionally, The Baseball Network had exclusive coverage windows; no other broadcaster could televise MLB games during the same night that The Baseball Network was televising games.

The arrangement did not last long; due to the effects of a players' strike on the remainder of the 1994 season, and poor reception from fans and critics over how the coverage was implemented, The Baseball Network would be disbanded after the 1995 season. While NBC would maintain rights to certain games, the growing Fox network (having established its own sports division two years earlier in 1994) became the league's new national broadcast partner beginning in 1996, with its then-parent company News Corporation eventually purchasing the Los Angeles Dodgers in 1998 (the company would sell the team in 2004).
