By 1977, CBS' NBA schedule was composed of six regionalized telecasts on Sundays. Not only that, the network would air one national game if they felt that match-up itself warranted national coverage. CBS also could stage doubleheaders and switch from a one-sided game to a close one. During this period, the network stopped airing any games during prime time prior to the NBA Finals. Instead, CBS started airing several West Coast games at 11:30 p.m. Eastern Time.
