RiffTrax

RiffTrax, run by MST3K stars Michael J. Nelson, Kevin Murphy, and Bill Corbett, produces funny audio commentaries for thousands of movies and shorts.

RiffTrax

RiffTrax was founded by Michael J. Nelson, former host and head writer of Mystery Science Theater 3000 (MST3K), after that show ended in 1999. The company's writers and performers — including Kevin Murphy (the voice of Tom Servo) and Bill Corbett (Crow T. Robot, v2.0) — produce comedic commentaries that can be synced to the listener's copy of a movie or embedded into the film itself. Wealth origin is the founders' MST3K careers. The firm's strategy is multi-format: it sells MP3 commentaries for major studio releases via its app, streams pre-merged riffed B-movies and educational shorts on its website and through partners like Amazon Prime, Tubi, and Pluto.tv, and produces physical media (DVD, Blu-ray). Geographic footprint is primarily North America, with live events broadcast to over 700 cinema screens nationwide via Fathom Events. Known co-investors or partners include Fathom Events for theatrical distribution; the company does not raise external capital from LPs for its productions. RiffTrax does not disclose revenue, AUM, or team headcount beyond its creative roster. The company is structured as a digital media publisher, not an investment firm. It also operates a Twitch channel and the RiffTrax channel on Samsung TV Plus. March 2025: RiffTrax presented its annual live show 'RiffTrax Live: The Wizard of Oz' in partnership with Fathom Events (per RiffTrax, March 2025). RiffTrax's structural differentiator is its direct-to-fan model: it bypasses traditional movie studios and distributors, generating revenue from consumer purchases and streaming licensing rather than from fund management fees or institutional capital. The core creative team controls all content decisions.
