According to a recent report from THR, it appears that The CW has officially ordered a Black Lightning pilot from Greg Berlanti. The project was originally in development at Fox but subsequently moved to The CW after Fox passed on the project due to its abundance of comic book properties -- not unlike Riverdale, or Supergirl's recent transition to The CW from CBS. It seems that the network is becoming the quintessential home for Greg Berlanti's comic book adaptations, and we're just fine with that. The report does not confirm whether or not Black Lightning will take place on Earth-1 alongside shows like Arrow and The Flash, but it would make sense for the show to exist in its own timeline and Earth if it was originally pitched to a different network. Besides, Barry Allen could always bring him to Earth-1 whenever they want to make a crossover happen anyway.
