It's the DCEU

The DC Extended Universe (DCEU) is a media franchise and series of superhero films and television series, distributed by Warner Bros. Pictures and based on characters that appear in American comic books by DC Comics. The shared universe, much like the original DC Universe in comic books and the television programs, was established by crossing over common plot elements, settings, cast, and characters. The films have been in production since 2011, and in that time, Warner Bros has distributed nine films, with several others in various stages of development. It is the eleventh-highest-grossing film franchise of all time, having grossed over $5.6 billion at the global box office. Its highest-grossing film is Aquaman, which earned over $1.15 billion worldwide, becoming the highest-grossing DC film to date.
