For much of the 1960s, ABC only televised Sunday afternoon games, including during the NBA Playoffs. This meant that ABC did not have to televise a potential NBA Finals deciding game if it were played on a weeknight. In 1969, ABC did televise Game 7 of the Los Angeles Lakers–Boston Celtics series in prime time on a weeknight. The following season, ABC aired the 1970 NBA Finals in its entirety, making it the first Finals series to have all games televised nationally.
