As newspapers around the world rush to erect paywalls to bolster their declining revenue - with Britain's Telegraph and Sun papers just the latest to join the parade, along with the Washington Post - there are a few holdouts who insist on generating revenue the old-fashioned way: namely, through advertising. One of the most prominent proponents of this model is the Daily Mail, which has become one of the world's largest news websites.

According to a report by Yahoo! News,Bloomberg told a reporter for The New York Post: "I've told your boss, I think he should stop twittering," at a news conference in Brooklyn.

George Galloway has called for the UK government to impose sanctions on Twitter unless it co-operates with the authorities on the detection of crime. The Respect MP described the microblogging service's failure to hand information to police as "reprehensible" and accused it of being focused solely on profit, The Daily Telegraph reports.

The Sun is reportedly following the Telegraph in charging readers for online access. The Telegraph revealed it was offering readers a choice of two different packages after using up their quota of 20 free stories a month. It was later reported that The Sun will introduce a paywall for its website later this year.

A tweet by comedian Alan Davies could cost him as much GBP200,000 in damages - almost half the number of people to which he retweeted a false allegation linking Lord McAlpine to a child abuse scandal last year.

A new Government amendment has been proposed which would exclude "small-scale" bloggers from the threat of exemplary damages if they refuse to join a new Royal Charter-backed press regulator. Justice minister Lord McNally urged the House of Lords to accept the change to the Leveson proposals in the Crime and Courts Bill in the light of concerns that bloggers would get caught up in laws intended to apply to larger organisations.

New research from BBC World News and BBC.com has found that almost half (42%) of 25 to 34 year olds are likely to turn to TV as their primary medium for finding out breaking news, with 66% then turning to the internet to find out more information. The study, carried out in conjunction with InSites Consulting, surveyed more than 3,600 owners of digital devices, and discovered that 43% of tablet owners watch more TV news than they did five years ago.

Google-owned video site YouTube recently announced that it sees around a billion unique users visit the site per month. Now, Experian Hitwise has broadened the net but narrowed the focus, finding that where just UK users were concerned, all of the web's video hosting sites see around the same number of visits. Furthermore, these video views are now accounting for five per cent of all web traffic from UK users; representing a 16% year-on-year increase.
