Superboy's popularity in Adventure resulted in the character receiving his own title in 1949, when superhero titles in general were losing popularity. Superboy became the star of the book, and would appear on each cover into 1969 (counting Superman on the covers of issues #354–355). Starman's and Sandman's series were canceled to make room for the new features, while Genius Jones moved to the comic the new arrivals had just vacated.

The series' focus gradually shifted to superhero stories starting with the debut of the Sandman in issue #40. In issue #12, while the series was briefly re-titled New Adventure Comics, Joe Shuster and Jerry Siegel introduced the first version of the character Jor-L as a science fiction detective in the far future the character would eventually become the alien father of Superman, although the first Superman story, in Action Comics #1, would not appear until more than a year after Jor-L's first appearance.
