By 1950, three more had joined that number and in 1970, there were still only eight major college bowl games. The number grew to eleven in 1976. At the birth of cable television and cable sports networks like ESPN, there were fifteen bowls in 1980. With more national venues and increased available revenue, the bowls saw an explosive growth throughout the 1980s and 1990s. In the thirty years from 1950 to 1980, seven bowl games were added to the schedule. From 1980 to 2010, an additional 20 bowl games were added to the schedule. Some have criticized this growth, claiming that the increased number of games has diluted the significance of playing in a bowl game. Yet others have countered that the increased number of games has increased exposure and revenue for a greater number of schools, and see it as a positive development. With the growth of bowl games, it became difficult to determine a national champion in a fair and equitable manner. As conferences became contractually bound to certain bowl games (a situation known as a tie-in), match-ups that guaranteed a consensus national champion became increasingly rare. In 1992, seven conferences and independent Notre Dame formed the Bowl Coalition, which attempted to arrange an annual No.1 versus No.2 matchup based on the final AP poll standings. The Coalition lasted for three years; however, several scheduling issues prevented much success; tie-ins still took precedence in several cases. For example, the Big Eight and SEC champions could never meet, since they were contractually bound to different bowl games. The coalition also excluded the Rose Bowl, arguably the most prestigious game in the nation, and two major conferences—the Pac-10 and Big Ten—meaning that it had limited success. In 1995, the Coalition was replaced by the Bowl Alliance, which reduced the number of bowl games to host a national championship game to three—the Fiesta, Sugar, and Orange Bowls—and the participating conferences to five—the ACC, SEC, Southwest, Big Eight, and Big East. It was agreed that the No.1 and No.2 ranked teams gave up their prior bowl tie-ins and were guaranteed to meet in the national championship game, which rotated between the three participating bowls. The system still did not include the Big Ten, Pac-10, or the Rose Bowl, and thus still lacked the legitimacy of a true national championship.
