As comic books grew in popularity, publishers began launching titles that expanded into a variety of genres. Dell Comics' non-superhero characters (particularly the licensed Walt Disney animated-character comics) outsold the superhero comics of the day.[12] The publisher featured licensed movie and literary characters such as Mickey Mouse, Donald Duck, Roy Rogers and Tarzan.[13] It was during this era that noted Donald Duck writer-artist Carl Barks rose to prominence.[14] Additionally, MLJ's introduction of Archie Andrews in Pep Comics #22 (December 1941) gave rise to teen humor comics,[15] with the Archie Andrews character remaining in print well into the 21st century.[16]
