With the establishment of DC as one of the major comic book companies and with many of the most marketable names in the early years of comics, it is sometimes considered the main company that other companies had to compete with. Companies tried different approaches, One that succeeded and often outsold DC for instance was Fawcett Publications who had a character who some consider similar to Superman who was an all-powerful hero with a supporting "family" known as Captain Marvel and the Marvel Family, whereas other companies such as Charlton Comics created entire new worlds preventing DC from attacking them with lawsuits. Further along in the Silver Age many of these companies failed or like Fawcett were sued out of existence. Thus although they had once been competitors, many of the soon public domain properties of Fawcett and Charlton were eventually revived and trademarked and seemingly taken under DC's control.
