Nielsen Online has released data from a new survey suggesting that premium content just might work, but it depends on the type of content.
27,000 consumers in 54 countries were surveyed. I don't know how this survey found people who actually said they would pay for things such as newspaper articles that they currently get for free, but they did.
Survey participants were most likely to shell out the dough for music and movies. Least likely was blogs.
Ironically, the reality is often the opposite, with consumers ditching premium newspapers for free, ad-supported ones while bloggers often monetize special pieces of content (courses, e-books, etc) for profit.
