He is most well known from his time as a Segment Producer on TechTV's The Screen Savers and later as the host of his own late night talk show Unscrewed with Martin Sargent.

Recurring callers included inventor Alex Chiu as well as the fictional characters Johnny O'Banion (portrayed by co-writer/producer Stewart Engesser), a Hollywood reporter and former Loni Anderson paramour, and karate master Rickey Kang (also played by Spieden).

The podcast was originally available in audio-only format, then offered an alternative video version consisting of a montage of still photographs relating to the topic discussed and taken at the recording session.

[6] He has reappeared on Revision3 show 'The Digg Reel' twice since he was laid off, once as acting co-host alongside Kevin Rose while regular host Andrew Bancroft was on vacation.

He appeared once more on The Digg Reel's 100th episode, in which he jokingly stated that he secretly lived within the walls of the Revision3 building, resulting from his supposed inability to get another job.

[7] The show aired for just shy of a year before going on hiatus in January 2010, following Martin's employment at Goodby, Silverstein & Partners in San Francisco.
