played many late-evening [Eastern/Central Time] games during the regular and postseason against West Coast teams in the western divisions of the National and American Leagues.) U.S. District Judge Suzanne B. Conlon issued a preliminary injunction in favor of Tribune and the Cubs on July 23, 1992, six weeks prior to an 18-9-1 motion of no confidence against Vincent among team owners on September 4. Impacts to baseball's attempts to curb superstation telecasts were felt following Vincent's subsequent resignation as MLB Commissioner on September 7, 1992; one week after his departure, the proposed blackout amendment failed to make a Cable Television Act reconciliation bill due to the lack of support for the provision in the Senate. The NBA also undertook actions to limit superstation telecasts of the league's games. In 1982, it began prohibiting television stations that reached at least 5% of all out-of-market cable households from airing games that conflicted with those shown on the league's national cable partners (at the time, ESPN and USA Network); this transitioned in June 1985 to a 25-game limit on the number of seasonal NBA telecasts that could be licensed to superstations (sixteen fewer than the 41-game maximum under existing NBA local broadcast rules). Concerned with the potential impact that the concurring returns of the Chicago Bulls and the Atlanta Hawks to WGN and WTBS, respectively, would have on its national contracts with NBC and ESPN, in April 1990, NBA Commissioner David Stern further reduced the amount of superstation-licensed NBA telecasts to 20 games per season. This sparked a 5½-year legal battle against the NBA by Tribune Broadcasting and Chicago Bulls parent Chicago Professional Sports L.P. The conspiracy and antitrust lawsuit filed by the co-plaintiffs in the United States District Court for the Northern District of Illinois on October 16, 1990, alleged that the 20-game limit was aimed at "phas[ing] out such superstations telecasts entirely in increments of five games each year over the next five years," a separate plan proposed by Stern that was never voted upon by NBA team owners. (The NBA contended the restriction was exempt from antitrust law under a provision of the Sports Broadcasting Act of 1961, which was deemed in later rulings to only be applicable to the sale or transfer a national game package to a television network and not those involving individual teams.) After four separate rulings in favor of Tribune and the Bulls issued by
