DC Screen Continuities

DC has three multi-character screen continuities:

a single TV series;
several interconnected TV series;
several interconnected feature films.

Earlier DC screen continuities include:

a ten film continuity (five Superman, one Supergirl and four Batman);
a Batman trilogy;
the Batman TV series;
the Gotham TV series;
three different earlier TV versions of Superman;
Wonder Woman on TV;
an earlier Flash TV series;
the film, Green Lantern;
the film, Constantine;
Swamp Thing in films and on TV;
Steel;
Superman and Batman in cinema serials;
animated versions.

There are others. These continuities feature several different versions of many comics-derived characters but I have lost interest in trying to keep count.
