Batman is a 1960s American television series, base on the DC comic book character Batman. It aired on the American Broadcasting Company (ABC) network for 2½ seasons from January 12, 1966 to March 14, 1968. Because the series had two weekly installments for most of its tenure, it contained the same number of episodes as a five-year or even a five-and-a-half-year run by today's standards (shooting 22-24 episodes per season).
