PEWInternet released a report last week stating that "65% of internet users have paid for online content", but unfortunately, the news is not all good as the breakdown of what they paid for is as follows:

* 33% of internet users have paid for digital music online
* 33% have paid for software
* 21% have paid for apps for their cell phones or tablet computers
* 19% have paid for digital games
* 18% have paid for digital newspaper, magazine, or journal articles or reports
* 16% have paid for videos, movies, or TV shows
* 15% have paid for ringtones
* 12% have paid for digital photos
* 11% have paid for members-only premium content from a website that has other free material on it
* 10% have paid for e-books
* 7% have paid for podcasts
* 5% have paid for tools or materials to use in video or computer games
* 5% have paid for “cheats or codes” to help them in video games
* 5% have paid to access particular websites such as online dating sites or services
* 2% have paid for adult content
Adult content is at the very bottom of this list with only 2%. That stat may not be correct as people may not have admitted to buying adult content...but still, that is incredibly low. Course, the good news is that people are willing to pay for online content, its just a matter of getting them something that they want to purchase!
