Funny how Static got a much bigger push.
He really didn't get a bigger push, he's just a better character and he debuted at the right time (plus there's some legal issues DC has with Black Lightning).
Static debuted right near the end of the comic book boom period and benefited greatly from that. A lot of people dug the character and he had a fairly successful run. Then Dwayne McDuffie locked up the TV deal and that shot his popularity into the stratosphere.
When Dwayne initially brought the character to tv execs they wanted to turn him white. Later in the shows run it was the highest rated show on Kids WB (beating out Pokemon) but for whatever reason nobody wanted to make toys based on the character so they lost funding and had to end it.
As for the Static Comic DC comics tried to censor one of the covers because it showed Static making out with his black girlfriend. DC claimed it was too risque even though at the time most of their comics were ass and titty shots.
