Marvel Comics is the brand name and primary imprint of Marvel Worldwide Inc., formerly Marvel Publishing, Inc. and Marvel Comics Group, a publisher of American comic books and related media. In 2009, The Walt Disney Company acquired Marvel Entertainment, Marvel Worldwide's parent company.
Marvel started in 1939 as Timely Comics, and by 1951 had generally become known as Atlas Comics. The Marvel era began in 1961, the year that the company launched The Fantastic Four and other superhero titles created by Steve Ditko, Stan Lee, Jack Kirby, and many others. The Marvel brand had been used over the years but solidified as the company's only brand within a couple of years.
