Micropayments: Would you pay 20p to read an article?
Found on BBC News on Tuesday, 20 November 2012

Consider this as a future: paying small amounts to read, watch and listen to content online. 20 pence (32 US cents) for a feature here, 10p for a news story there.
As the name suggests, paywalls keep all the valuable content under lock and key. Access can be gained via a subscription, much in the way a print subscriber can arrange to get a newspaper delivered every day to their home.
I doubt it will be easy to convince users to pay for online content, especially since the free spreading of information is a key element of the Internet.
