As more conservative owners left the NHL, a younger guard that was more receptive to expansion came into the league. By 1963, when Rangers governor William M. Jennings first introduced to his peers the idea of expanding the NHL, Major League Baseball and the National Football League were adding teams, while the American Football League was becoming an attractive alternative to the NFL. Jennings proposed that the NHL add two new teams on the American West Coast for the 1964-65 season, basing his argument on concerns that the Western Hockey League intended to operate as a major league in the near future and possibly compete against the NHL for talent; he also hoped that a West Coast presence would make the NHL truly national and improve the league's chances of returning to national television in the United States (its broadcast deal with CBS expired in 1960). While the governors did not agree to Jennings' proposal, the topic of expansion arose every time the owners met from then on out. In 1965, the league decided to double in size by adding six teams, and in February 1966, expansion franchises were awarded to Los Angeles, Minnesota, Philadelphia, Pittsburgh, St. Louis, and the San Francisco-Oakland area. The six new clubs would begin play in the 1967–68 season. Thus, with Toronto's six-game victory over Montreal in the 1967 Stanley Cup Finals, the Original Six era came to a close.
