Beginning in 1973 through 1986, The Dynamic Duo appeared on various incarnations of the Super Friends animated series (covered in detail in the History of the Justice League) as well as the live action variety show.
During the run, only once did The Boy Wonder appear alone, not just tagging along Batman.
Notable Bat villains included The Riddler and Scarecrow (members of the Legion of Doom) and eventually the Joker and Penguin during the Galactic Guardians years.
Over 13 seasons, Batman was featured alongside other "Friends" in most of the 100+ episodes produced.
Oh, and by the way, of course there was a cereal tie-in.
