A webcam model (colloquially, camgirl, camboy, or cammodel) is a video performer who streams on the Internet with a live webcam broadcast. A webcam model often performs erotic acts online, such as stripping, masturbation, or sex acts in exchange for money, goods, or attention. They may also sell videos of their performances. Once viewed as a small niche in the world of adult entertainment, camming became "the engine of the porn industry," according to Alec Helmy, the publisher of XBIZ, a sex-trade industry journal.
As many webcam models operate in the comfort of their own homes, they are free to choose the amount of sexual content for their broadcasts. While most display nudity and sexually provocative behavior, some choose to remain mostly clothed and merely talk about various topics, while still soliciting payment as tips from their fans. Webcam models are predominantly women, and also include noted performers of all genders and sexualities.
