Williams Street Productions, LLC,^[1] d/b/a Williams Street and formerly known as Ghost Planet Industries, is an American animation and live action television production studio owned by the Warner Bros. Television Studios division of Warner Bros., a unit of Warner Bros. Discovery. The studio is the in-house production arm of Adult Swim (the programming block on Cartoon Network). Mike Lazzo and Keith Crofford oversaw operations for the building for most of its existence.

On December 16, 2019, co-founder Lazzo retired from the company,^[2] with business partner and co-founder Crofford retiring the following year.^[3] Michael Ouweleen was named president of Adult Swim on April 29, 2020.^[4]

From November 27, 2019 to July 1, 2020 and since May 13, 2022, Ouweleen was named president of The Cartoon Network, Inc., which also oversees Adult Swim.^[5]

The current name of the company originates from the location of its headquarters building – which is also the home office for Cartoon Network and Adult Swim – at 1065 Williams Street NW in Atlanta, Georgia near the current offices of TBS and TNT on Techwood Drive.^[6] The facility began as a carpet factory and was purchased by Turner as overflow offices for, among other things, set building and woodworking facilities, as well as CNN Field Engineering. Soon after CNN moved into the CNN Center in downtown Atlanta in the early 1980s, other Turner operations moved into the Techwood campus, an old country club which became the first headquarters for CNN.^[6] The street is named for early Atlanta settler Ammi Williams.

The company's original name, Ghost Planet Industries, came from Space Ghost's fictional planet, where the animated talk show Space Ghost Coast to Coast was purportedly filmed.^[7]

The studio's production logo features a wavy, blurred gray image of Space Ghost's fictional studio, with the words "Williams Street" beneath it. The soundtrack of Jack Webb's Mark VII Limited's production logo – a rumbling drum roll and two clinks of a hammer – is often used while the GPI/Williams Street production card is shown.^[8]

1065, the street number for Williams Street, is also the hull number for FishCenter Live's USS FishCenterprise (a parody of the original Star Trek's USS Enterprise).^[39]
