Marvel isn't as crazy about canon immigrants as DC is. This means that there are fewer of them, but it also means that the characters that do immigrate generally become popular and are used in the long-term.
Videoman first appeared in the Spider-Man and His Amazing Friends episode of the same name (1981) as a creation of Electro, and then later as an actual supervillain (1982), and later still as a superhero (1983). He made the jump to comics in Spider-Man Family Featuring Amazing Friends #1 (October 2006).
