xHamster is a pornographic media and social networking site headquartered in the Cypriot city of Limassol, with offices in Houston, Kyoto, and London. xHamster serves user-submitted pornographic videos, webcam models, pornographic photographs, and erotic literature, and incorporates social networking features. xHamster was founded in 2007. With more than 10 million members, it is the third most popular pornography website on the Internet after XVideos and Pornhub.
The site produces The Sex Factor, a reality TV series in which men and women compete to become porn stars. The site has been targeted as part of malvertising campaigns, and some governments have blocked xHamster as part of larger initiatives against Internet pornography.
