From October 1991 through July 1992, Ancier served as the television consultant to the Democratic National Committee, specifically to advise on the television presentation of the Democratic Convention in New York City and reporting to DNC Chairman Ron Brown. In that role, Ancier introduced political convention format innovations, such as a 56-screen "videowall" integrated into the convention podium and program, to such forums for the first time. Later on, Ancier's production company developed and produced the talk show Jane Pratt, which debuted in mid-March 1992 on WNYW-TV in New York City and was intended for nationwide launch. However, despite good ratings, the show ended after only 11 weeks in production, as co-producer and distributor 20th Television felt it was too expensive for them to seek a return on their investment in the program.[9][10]
Also in late 1992, Ancier co-created and executive produced Ricki Lake[7] with former Donahue producer Gail Steinberg. The tabloid talk show aired for 11 seasons from 1993 to 2004.
Ancier returned to The WB as co-chairman in September 2003,[citation needed] then became the Chairman of the WB Television Network from May 2004 until its merger with UPN to form The CW in September 2006,[12] during which Supernatural and One Tree Hill were launched.[citation needed] He was transferred to run In2TV, the Warners/AOL broadband television network.[12] Through the Garth Ancier Company, he was developing a talk show at the pilot stage while negotiating a potential network, cable and first-run syndicated shows deal with Telepictures and Warner Horizon as of October 2006.[13]
He served as first president of BBC Worldwide America from February 2007–March 2010,[12] where he launched Top Gear, Torchwood, and DC produced BBC World News America (BBC's first US produced daily newscast) on BBC America. Ancier also moved BBC's iconic Doctor Who series from the Syfy network to BBC America and prepared CBeebies for a US launch. Ancier was able to increase by 78% BBC Worldwide America's profit and was to continue to hold a director's seat on its board after his departure from management was planned for March 2010.[14]
In April 2013, Ancier formed Zeus Media Partners, Inc. as a retro cable network company to provide four decade focused channels (1960s–1990s), later called The Quad.[15][16]
He is also known for being one of only two people (the other being Fred Silverman) to have programmed three of the five US broadcast television networks (founding programmer at Fox, founding programmer at The WB (now The CW), and NBC Entertainment).
