Syndication and DVDs
The radio series was one of the most extensively preserved programs of its era, with the archive almost complete from 1936 onward and several episodes existing from before that (including the 1932 premiere). As with the radio shows, most of the television series has lapsed into the public domain, although several episodes (particularly those made from 1961 onward, including the entire NBC-TV run) remain under copyright. During his lone NBC season, CBS aired repeats on weekdays and Sunday afternoons. 104 episodes personally selected by Benny and Irving Fein, Benny's associate since 1947, were placed into syndication in 1965 by Universal/MCA television. Telecasts of the shows in the late evening were running as late as 1966.  Four early 1960s episodes were rerun on CBS during the summer of 1977. Edited 16mm prints ran on the CBN Cable Network in the mid 1980s. Restored versions first appeared on the short lived HA! network in 1990. As of 2011, the series has run on Antenna TV, part of a long term official syndication distribution deal. The public domain television episodes have appeared on numerous stations, including PBS, while the radio series episodes have appeared in radio drama anthology series such as When Radio Was.  Public domain episodes have been available on budget VHS/Beta tapes (and later DVDs) since the late seventies. MCA home video issued a 1960 version of the classic "Christmas Shopping" show in 1982 and a VHS set of ten filmed episodes in 1990. In 2008, 25 public domain episodes of the show, long thought lost, were located in a CBS vault. The Jack Benny Fan Club, with the blessing of the Benny estate, offered to fund the digital preservation and release of these sealed episodes. CBS issued a press statement that any release was unlikely. June 2013 saw the first official release of 18 rare live Benny programs from 1956 to 1964 by Shout Factory. This set, part of Benny's private collection at the UCLA film and television library, included guest shots by Jack Paar, John Wayne, Tony Curtis, Gary Cooper, Dick Van Dyke, Rock Hudson, Natalie Wood, President Harry Truman and the only TV appearance with longtime radio foe Ronald Colman.
