Did You Know?

As Superman fans know, "Brainiac" was the superintelligent villain in the Action Comics series and its spin-offs. You don't need x-ray vision to see the connection here - etymologists think Superman's brainy adversary was probably the inspiration for our term "brainiac." We didn't coin the term right away though. The comic-book series was launched in 1938, and the general use of "brainiac" was first recorded in print in 1982.
