Sherdog was created by photographer Jeff Sherwood (nicknamed "Sherdog") in 1997 and was later refined with the help of Garrett Poe. Sherdog features MMA news, individual records of fighters, reviews and previews of MMA events, interviews with fighters and referees, user forums, divisional and pound-for-pound fighter rankings, and original radio programs.
Sherdog is additionally home to the Sherdog Radio Network, an internet-only sports talk network featuring Sherdog writers and staffers. Weekly programmes have included The Savage Dog Show hosted by Greg Savage and Jeff Sherwood, Beatdown hosted by TJ De Santis and a number of co-hosts, It's Time hosted by Bruce Buffer and The Jordan Breen Show.
Until recently, the standard schedule included Beatdown on Monday, Wednesday and Friday, It's Time on Tuesdays, Cheap Seats on Tuesdays and Thursdays, and The SRN Rewind every Sunday evening. Also included for big events were SRN Roundtables providing previews and "Beatdown After the Bell" for post-fight recaps.
As of April 8, 2016, the SRN was rebuilt after Jeff Sherwood and his namesake website parted ways. The current lineup of programming includes Cheap Seats with Jordan Breen and Greg Savage on Mondays and Wednesdays, TJ & The Tooth with TJ De Santis and Nick "The Tooth" Gullo on Tuesdays, and The Neutral Corner hosted by MMA veteran Yves Edwards. Still standard for high-profile events are Jack Encarnacao's SRN Roundtables providing previews and TJ De Santis' "Beatdown After the Bell" for post-fight recaps. While not officially a part of the Sherdog Radio Network, the SRN feed additionally inclues Press Row audio blogs starring Jordan Breen and various guests in the world of MMA media. While not officially cancelled, Jack Encarnacao's The SRN Rewind has been on an extended hiatus, and the flagship show Beatdown has been discontinued as a live radio show after the exiting of Jeff 'Sherdog' Sherwood.
Sherdog has additionally affiliated with ESPN to provide extensive MMA content for their site. The deal includes ESPN sharing Sherdog's extensive Fight Finder database. The deal would additionally include the Sherdog Radio Network being part of ESPN's podcast center.
The website additionally has a xenForo forum section composed of more than 60 thousand members from all over the world.
The site hosts free live streams of mixed martial arts events from organisations such as Palace Fighting Championships, Wargods and M-1 Global.
