During the 20th century, DC Comics' Superman was easily the worlds best known (and most popular) comic book hero. In the 21st century, that is gradually shifting to Spider-Man, and that is representative of how Marvel Comics has overtaken what it used to call "the Distinguidhed Competition" (i.e., DC Comics).
Brief history of Marvel Comics
Marvel began as Timely Comics in 1939, morphing into Atlas Comics in the 1950s, and then into Marvel Comics by 1961 with Fantastic Four #1. In 1968, Marvel was sold to Perfect Film and Chemical Corporation (this company changed its name in 1973 to Cadence Industries). In 1986 Marvel was sold to New World Entertainment, and then again in 1989 to MacAndrews and Forbes run by Ronald Perelman. In 1997 the company was purchased by Toy Biz which was owned by Isaac Perlmutter and Avi Arad. In 2009, Disney bought the company.
(Atlas was briefly reborn in 1974 by Timely/Atlas/Marvel original owner Martin Goodman who ran the new, not-Marvel company for 18 months under the main company name of Seaboard Periodicals.)
