This is pretty hard to believe, considering the immense popularity of the "Big Game" today. The first six Superbowls were blacked out on local television in the host city and 75 miles from it. The standard NFL rule back then was that the home market for all regular season and playoff games would be blacked out even if the game was sold out. The 1973 Superbowl was televised locally on the condition that all tickets would be sold 10 days before kickoff. Beginning in 1974, the league began a policy where home games could be broadcast locally if the game was sold out 72 hours before kickoff.
