Superboy was created in the early 1940's by Superman's original creators, Jerry Siegel and Joe Shuster, to be the Man of Steel when he was a boy.

Superboy first appeared in MORE FUN COMICS #101, Jan-Feb, 1945, in a story by Siegel and Shuster.

Proving to be a popular incarnation of Kal-El, Superboy next began appearing in ADVENTURE COMICS with issue #103, April, 1946.  Superboy would star in this title for the next 23 years.  The "Tales of the Legion of Super-Heroes" began in issue 300 and ran until #380, with Supergirl taking over the title in #381.

Superboy's own eponymous title began in 1949 with the March/April issue.  The Legion began appearing in Superboy in the early 1970's.  Superboy's last solo story in his own title was in SUPERBOY #196, when the Legion began co-headlining the book.

It was through Superboy's own comic that DC launched the Legion of Super-Heroes.

The Legion took over the title with issue #259.  Superboy then returned to ADVENTURE COMICS, and later to a second series.

There was even a thrid Superboy series based upon the syndicated TV series from the 1980's.

However, in 1986, DC destroyed its nearly 50-years of comic-book history, wiping many characters-- including Superboy, his faithful dog Krypto, and Supergirl-- completely out of existence.

Truly, comics are the poorer for it.
