Pornography on cellular phones

Pornography on cellular phones, already a multi-million dollar business in Europe, is showing signs of coming to the United States. Bigger screens and faster networks make video feeds, including x-rated fare, a growing opportunity for the cellular industry, and executives are wondering whether they can afford to stay out of it. American cellular companies and their trade groups are looking at ratings system similar to movies for marking content available on phones, a first step towards what is sure to be a politically charged debate over whether cell phone sex sells in the United States alongside ring tones and video games.
