called the Oakland "Señores", the Oakland Raiders officially joined the AFL on January 30, 1960. The AFL's first major success came when the Houston Oilers signed Billy Cannon, the All-American and 1959 Heisman Trophy winner from LSU. Cannon signed a $100,000 contract to play for the Oilers, despite having already signed a $50,000 contract with the NFL's Los Angeles Rams. The Oilers filed suit and claimed that Rams general manager Pete Rozelle had unduly manipulated Cannon. The court upheld the Houston contract, and with Cannon the Oilers appeared in the AFL's first three championship games (winning two). On June 9, 1960, the league signed a five-year television contract with ABC, which brought in revenues of approximately $2.125 million per year for the entire league. On June 17, the AFL filed an antitrust lawsuit against the NFL, which was dismissed in 1962 after a two-month trial. The AFL began regular-season play (a night game on Friday, September 9, 1960) with eight teams in the league – the Boston Patriots, Buffalo Bills, Dallas Texans, Denver Broncos, Houston Oilers, Los Angeles Chargers, New York Titans, and Oakland Raiders. Raiders' co-owner Wayne Valley dubbed the AFL ownership "The Foolish Club", a term Lamar Hunt subsequently used on team photographs he sent as Christmas gifts. The Oilers became the first-ever league champions by defeating the Chargers, 24–16, in the AFL Championship on January 1, 1961. Attendance for the 1960 season was respectable for a new league, but not nearly that of the NFL. In 1960, the NFL averaged attendance of more than 40,000 fans per game and more popular NFL teams in 1960 regularly saw attendance figures in excess of 50,000 per game, while CFL attendances averaged approximately 20,000 per game. By comparison, AFL attendance averaged about 16,500 per game and generally hovered between 10,000 and 20,000 per game. Professional football was still primarily a gate-driven business in 1960, so low attendance meant financial losses. The Raiders, with a league-worst average attendance of just 9,612, lost $500,000 in their first year and only survived after receiving a $400,000 loan from Bills owner Ralph Wilson. In an early sign of stability, however, the AFL did not lose any teams after its first year of operation. In fact, the only major change was the Chargers' move from Los Angeles to nearby San Diego (they would return to Los Angeles in 2017). On August 8, 1961, the AFL
