In 1969, Summerall took part in NBC's coverage of Super Bowl III. NBC used Summerall to provide an "NFL perspective" on the coverage. This was due in part to the fact that NBC was at the time, the network television provider of the American Football League (whereas CBS was the network television provider for the pre-merger National Football League). In return, for CBS Radio's coverage of Super Bowls I, II and IV, they used Tom Hedrick, normally the radio voice of the Kansas City Chiefs, to provide an "AFL perspective" for their coverage.
