An institution in American TV and sports since 1970, when ABC won partial rights to NFL broadcasts - this Roone Arledge idea of weekly prime-time football (after CBS had done it on a testing-the-waters sporadic basis) won over the NFL suits. The show's as much in the broadcast booth as on the field, enhancing the celebrity of its announcers, which over the years have included Howard Cosell, O.J. Simpson, and Frank Gifford.
