In the 21st century, an online service has the potential to garner hundreds of thousands of hits if it is social networking enabled. Now after a decade of connecting with real world friends online, people suddenly have the desire to befriend strangers.
Though not the first chat service to pair up random strangers, Chatroulette did add video zing to the otherwise bland random text chats.
Omegle has been around for a while connecting random strangers in text chats.
They have added the video chat option very recently.
Each random chat conversation is referred to as a game and you can restart a new game at any time.
