Damn porn everywhere.
http://www.dailyfinance.com/2009/07/07/porn-hits-wireless-but-where-are-the-profits/The dirty little secret behind many new technologies is porn. From cinematography to video cassettes and the Internet, pornography has been a key driver of growth. Now, porn is showing up on mobile phones and it's relentlessly wearing down the wireless carrier's bandwidth.
In Japan, where third-generation wireless networks are more pervasive than in the U.S., buffet-style wireless internet access (all you can eat) is causing demand for porn to surge , while putting pressure on margins and on the networks themselves.
Japanese carriers NTT DoCoMo (DCM) and KDDI (KDDIY) now say that while the porn frenzy does bring in profits, their networks are under so much strain that they are kicking around the idea of putting some limits on how much bandwidth heavy users can actually have.
It's a problem that U.S. carriers could soon face. Unlike other sectors of the adult entertainment industry, Juniper Research estimates that global revenues for handheld hotties could reach $4.9 billion by 2013, up about 75 percent from about $2.8 billion in 2008. This stands in stark contrast to both traditional online delivery and DVD porn, where sales have recently been falling.
