Since his first appearance in 1939, Batman has been adapted into such media as film, radio, television, and video games, as well as numerous merchandising items.
A number of Batman theatrical films have been made. There have also been several attempted projects during the hiatus between Batman & Robin and Batman Begins.
Beginning in March 1945, Batman and Robin made regular appearances on the radio drama The Adventures of Superman on the Mutual Broadcasting System. Efforts were made to launch a Batman radio series in 1943 and again in 1950, but neither came to fruition.
In 1989, an original radio drama, Batman: The Lazarus Syndrome, was produced by Dirk Maggs for BBC Radio 4.
A second Maggs production aired on BBC Radio 1 in 1994, this time adapting the comic book storyline Batman: Knightfall. It was adapted, produced and directed by Maggs—with music composed by Mark Russell—who had also made Superman: Doomsday & Beyond on BBC Radio 5. This show, however was not commissioned of its own, but rather to be three-minute episodes on the Mark Goodier Show. This meant it was written with a sense of immediacy; having to make an instant effect and each three-minute segment contains a major plot development or sound effect stunt and ends on a cliffhanger. DC acknowledged the effort in an issue Shadow of The Bat by having villains jump past a sign reading "Dirk Maggs Radio". Michael Gough reprised the role of Alfred Pennyworth from the Burton/Schumacher film series.
From 1943 to 1946, Batman and Robin appeared in a syndicated daily newspaper comic strip produced by the McClure Syndicate. Other versions appeared in 1953, 1966, and 1989. The original run is collected in the book Batman: The Dailies. One more comic strip series ran briefly after the success of the 1989 film.
