 The show was canceled following a lawsuit filed by Warner Brothers  (the company that owned the Superman "family" of characters) against  the Salkinds who had leased the rights in the early 1970s and made  the "Superman"(Christopher Reeves) film series. The Salkinds  produced the first 3 films, and sold the rights to "Cannon/Golan  Globus Production" who released "Superman IV." WB claimed that they  had first shot at making a series (the show was distributed through  Viacom). The case was settled and the rights officially reverted to  WB and the show has not been rerun in North America since, although  a DVD release of the first season did occur in 2006.
