#If we disqualify the Tommy Westphall Universe… If we only consider a crossover universe where every show is intended to be in continuity with every other show (thus disqualifying The Tommy Westphall Universe, since for instance, *CSI: Miami* as it's own show is not intended to be in continuity with either *The Adventures of Superman* or *The Addams Family*), then the largest would be: ##The **[Super Sentai][1]** franchise (41 TV Shows and Growing) English speakers may be more familiar with *Power Rangers*, which takes fighting footage from this Japanese series and dubs it in English while splicing in original English footage. It began in 1975 with *[Himitsu Sentai Gorenger][2]* and now produces a new show every year, with the 2017-2018 show being *[Uchu Sentai Kyuranger][3]*. The 35th show (*[Kaizoku Sentai Gokaiger][4]*) was an anniversary show that explicitly showed that it was in continuity with all the previous shows, with all the protagonists appearing together (played by suit actors, which also happened in the original shows). Some of the non-suit actor original cast members also reprised their roles over the course of the series. [![The first 34 Super Sentai][5]][5] Each subsequent show is also in continuity with the show before it, with the final shot of each show showing a [hand-off][6] between the Red Ranger of the current show and the Red Ranger of the next show. ##If we count movies, the Super Sentai, Karen Rider, and Metal Heroes shared universe (84 TV Shows) You said that movies don't count for this purpose, but in recent years, the *Super Sentai* shows have had Japan-only theatrical movies where the current show's cast teams up with the previous show's cast. One such movie was *[Kamen Rider × Super Sentai × Space Sheriff: Super Hero Taisen Z][7]*, which is a crossover between the *Super Sentai* franchise, the *[Kamen Rider][8]* franchise (26 shows), and the *[Metal Heroes][9]* franchise (17 shows). So if movies were allowed, this would be a crossover universe, where every show is intended to be in continuity with every other, with **84 shows** at the time of this writing.
