On October 13, 1971, the World Series held a night game for the first time. Commissioner Bowie Kuhn, who felt that baseball could attract a larger audience by featuring a prime time telecast (as opposed to a mid-afternoon broadcast, when most fans either worked or attended school), pitched the idea to NBC. An estimated 61 million people watched Game 4 on NBC; TV ratings for a World Series game during the daytime hours would not have approached such a record number. In subsequent years, all weekday games would be played at night.
