When Carter discovers that Blipverts are killing people, Grossberg orders Lynch to prevent Carter from getting out of the building. Knocked unconscious, Carter's memories are extracted into a computer by Lynch in order to determine whether Carter uncovered Grossberg's knowledge of the danger of Blipverts. The resulting computer file of the memory-extraction process becomes Max Headroom, making Grossberg directly responsible for the creation of the character. In the end, Grossberg is publicly exposed as responsible for the Blipverts scandal, and is removed as chairman of Network 23. A few episodes later, in "Grossberg's Return", Grossberg reappears as a board member of Network 66. Again, he invents a dubious advertising medium and convinces the chairman of the network to adopt it. When the advertising method is shown to be a complete fraud, the resulting public reaction against the network leads to the chairman being removed, and Grossberg manages to assume the chairmanship. When under stress, Grossberg exhibits a tic of slightly stretching his neck in his suit's collar, first seen in episode 1 when he confronts Lynch in his lab regarding Max retaining Carter's memory about the blipverts. In the UK telefilm "Max Headroom: 20 Minutes Into the Future" upon which the American series was based, the character was called Grossman and was played by Nickolas Grace. Rocket portrayed Grossberg as an American yuppie with a characteristic facial and neck-stretching twitch. The series was based on the Channel 4 British TV film produced by Chrysalis, "". Cinemax aired the UK pilot followed by a six-week run of highlights from "The Max Headroom Show", a UK music video show where Headroom appears between music videos. ABC took an interest in the pilot and asked Chrysalis/Lakeside to produce the series for American audiences. "Max Headroom: 20 Minutes into the Future" was re-shot as a pilot program for a new series broadcast by the U.S. ABC television network. The pilot featured plot changes and some minor visual touches, but retained the same basic storyline. The only original cast retained for the series were Matt Frewer (Max Headroom/Edison Carter) and Amanda Pays (Theora Jones); a third original cast member, W. Morgan Sheppard, joined the series as "Blank Reg" in later episodes. Among the non-original cast, Jeffrey Tambor co-starred as "Murray", Edison Carter's neurotic producer. The show went into production in late 1986 and ran for six episodes in the first season and eight in season two.
