Webcam modeling, or camming, has become an increasingly popular career among men and women all over the world. Not because it's easy, but because it's lucrative and can be easily done at home by anyone.

For just a few hours of work, one can make up to 500 a day. Some models even claimed to have earned 4 figures amounts from a single show.

In 2013, the New York Times reported that the annual revenue of a popular adult cam site was estimated at over $1 billion. It also revealed that live cam has become a profitable part of the adult entertainment industry.

The porn industry has always been a lucrative business but the recent popularity of tube sites that offer free content had an impact financially. Camming, which used to be a niche market, became a huge industry on its own.

It also changed the way adult performers work. Unlike pornstars, Cam models often work independently and they get to choose where or when to work.

They don't need adult production companies or talent managers to get work. Instead, they rely on the adult cam sites to be the middlemen and at the same time promote their shows.

The camming industry has become so successful that even big-name adult performers began offering webcam shows. Like porn sites, webcam shows also offer a wide array of models, niches, and allows viewers to direct the show.

So, you're probably wondering how exactly do webcam models earn money?
