Marvel Comics continued it meteoric foothold in the comics industry. The 1980s saw some continued advancement and major changes (for the good or bad may depend on your point of view).
It was at this time period that Jim Shooter was Marvel's Editor-in-Chief. Shooter had, what many consider, a controversial personality, but he cured many of the procedural ills plaguing Marvel at the time (including repeatedly missed deadlines). He continued to oversee a creative renaissance at the company.
This renaissance included institutionalizing creator royalty and starting the Epic imprint for creator-owned material in 1982. But, in the long run, Shooter was still accused by many creators, especially near the end of his tenure, of exercising his job in a draconian manner and interfering with the writers' creative processes.
