Williams Street is a production company of Cartoon Network. Williams Street was formerly known as Ghost Planet Industries after Space Ghost's show in 1994-1999. All of Adult Swim is produced by Williams Street. The two people that are mainly responsible for watching over the corporation is Mike Lazzo and Kieth Crofford.

The name of the company is mainly named after the street that it lies on which is Williams Street in Atlanta, Georgia. This company is in the same building of Ted Turner who founded TBS, CNN and Cartoon Network.

The Building in the logo is a an animated version of the studio it started in. The building in real life is just a little different then the logo on TV. For Example: The building says TBS on the front, the building is much longer, it's more elevated in the center. The companies' building is right across the street from TBS headquarters.

The audio in the background of the logo is created by Jack Webb's production company Mark VII Limited.

The Williams Street logo is shown for about five seconds, and old shows are occasionally followed by a vanity card of a skull and crossbones with the old Cartoon Network symbol on the mouth, which was ended in 2004. The symbol was not used until after Ghost Planet Industries.

In Season 5, it will co-produce new episodes of Samurai Jack with Cartoon Network Studios.
