Williams Street West was a short lived studio subsidiary to Williams Street located in Los Angeles, and run by Space Ghost Coast to Coast executive producer Matt Harrigan. Before this, Matt was a writer for various Viacom shows including Celebrity Deathmatch and KaBlam!. With this setup, Matt was able to write and produce the last season of Space Ghost without needing to return to Atlanta. Of course, after the season was over, Matt did return to Atlanta, and thus Williams Street West was closed after less than a year in operation. It's unknown whether this studio will re-open in the future.
The Williams Street West logo is similar to the Williams Street logo, but the building is in reverse, and uses a slightly different filter and different font; however the same "Mark VII Limited" soundbyte is used.
