There are a number of popular, commercial webcam websites that allow people to openly masturbate on camera while others watch them.
Using similar sites, couples can also perform on camera for the enjoyment of others.
Cybersex is commonly performed in Internet chat rooms (such as IRC, talkers or web chats) and on instant messaging systems.
It can also be performed using webcams, voice chat systems like Skype, or online games and/or virtual worlds like Second Life.
Cybersex differs from phone sex in that it offers a greater degree of anonymity and allows participants to meet partners more easily.
