With the rise of television, beginning in 1952 and continuing through the early 1970s, studios tried to bring movie audiences back to theaters by making widescreen epics, again using the "roadshow" formula. Films shot in 3D sometimes were also shown in a roadshow format with intermission, regardless of actual length, as well as many films shot in various larger widescreen processes, such as CinemaScope, Todd-AO, MGM Camera 65, and Super Panavision 70 were given roadshow presentations, as well as films that were blown up to 70mm from the 35mm negative. As a result, there was an avalanche of roadshow films during those decades, often more than one in a single year.
