From the Hero Games website:
Digital Hero is a bi-monthly e-zine for all aspects of the HERO System. No matter what type of character, genre, or setting you like to play in, Digital Hero has tons of stuff you can use!
Although archived and still available on the Hero Games website, Digital Hero is no longer in active publication. (Issue #1 was released June 1, 2002, and the last issue, #47, was released January 1, 2008.)
Digital Hero was a descendant of the house organ on an earlier Hero Games incarnation, Adventurers Club Magazine.
