Erection on webcam
Tips are electronic tokens that viewers can buy from a camming website, and then give to the models during live performances.
The tokens can also be used to buy videos or souvenirs of the model.
However this is not the first time that conversational interaction had become a boon for the erotic entertainment industry.
Todd Blatt, who once produced pornographic movies in California and has several Ferraris to show for it, declared: "If you’re the middle guy who has been eating off this industry for 20 years, it’s a big change.
Within public chat rooms the audience can see tips and viewer comments as scrolling text which appears next to the real-time video stream.
Camgirls will frequently read and respond to the scrolling viewer comments.
The websites provide the transactional platform, and then collects and distributes a percentage of the tips to the models.
For public chat rooms, the model's portion of a tip is a little less than half.
