The music industry is battling to stop piracy through Russia's largest social network so that it can turn the country from a digital backwater in to a top music market. VKontakte, which is often called a Facebook copycat for its similar features and design, includes built-in file sharing. In a case brought by one label group, Gala, St Peterburg's commercial court in January ruled vKontakte in breach of copyright. That buoyed labels' global representative group, the International Federation of the Phonographic Industry. But now an appeal sought by vKontake is set to begin on May 17, and labels remain frustrated.

The hacking group Anonymous is threatening to launch online attacks every weekend after being charged with disrupting access to the British Home Office website. Twitter messages warned of the attack on 4 April. The site was inaccessible around 21:00 BST on Saturday and was patch from 05:00 on Sunday. One message on Twitter said it was a protest against "draconian surveillance proposals" but another claimed it was over extradition from the UK to the U.S.

VisitBritain's CEO tells an Institute of Travel and Tourism dinner audience that activity on sites like Facebook and Twitter will make a trip to London more appealing because of positive updates on news feeds. A trip into the city during the games can be seen as being "tricky" by those outside the capital. Sandie Dawe says social media will help combat this view, explaining, "I hope that people will be tweeting and Facebooking I'm having the time of my life, this is cool".

Visible only from the upper deck of buses, 30 LED screens have been installed by a collaborative public art project. The screens, which display animated gifs submitted by the public, hook up over 3G to a central server that distributes the image files to 20 boroughs across the capital. Each has a 10fps 256 x 80 display in monochrome red and black, but with variable brightness. The project's originator says, "We chose sites for various reasons and as you can see some are quite remote -- we didn't want to just be on Regent Street, we wanted to reach people …

The operator has announced a six-month trial for corporate users that will provide them with priority access to its mobile network. The company stressed that other customers will not be disadvantaged by this prioritisation, which will be offered free to corporate customers that have subscribed to one of Vodafone's two premium data plans used in laptops or tablets, but not smartphones. Vodafone previously tested a network priority service with business users in Spain.

The music video site, now a year old, says its UK users streamed 177 million videos in January. The report, which covers shows that while mobile streaming is still a relatively small part of Vevo's business, mobile use among users is growing fast. Mobile streams have doubled since it launched in the UK to 12.4 million for January 2012, while the mobile app has been downloaded 1.4 million times.

ISPs and device makers would be forced to filter adult content under a new bill presented to the House of Lords. The Online Safety Bill, raised in the Lords by Baroness Howe of Ildicote, asks for ISPs and mobile operators to "provide a service that excludes pornographic images" and for device makers to include ways to filter content at the point of purchase. The proposal is a Private Members Bill, which rarely make it into law without Government support, and has yet to be subject to any debate.

Mobile operators are now planning the deployment of LTE services across 300 German cities by the end of the year, a report from German ICT trade group Bitkom says. LTE reaches 13 million households in the country. By the end of 2012 more than 50 per cent of German households will have access to LTE. Bitkom said that for operators to meet their LTE licensing conditions they were first required to deploy the technology across rural areas that had no access to broadband services.

Only the automotive sector bucked the trend, getting the highest engagement on Tuesdays. Otherwise, fast moving consumer goods and telecoms, especially, were most likely to be engaged by fans on social media on Sundays. Socialbakers, which conducted the research, said brands "should consider posting their most compelling content at times of peak engagement to ensure the greatest online brand buzz". It also found that the responsiveness of brands to fan posts on Facebook is on the up, with response rates up 15.5% since October last year, when just 5% of posts elicited a response from a brand.

Chat software provider Netop has found a huge gap between public demand of live chat to solve customer service issues and its availability and that's a problem since customers prefer to engage online rather than leaving home or waiting on phone queues. Ninety-three percent of UK businesses do not use live chat as part of their customers' service experience. Fifty-four percent of consumers surveyed (of 2,000) said live chat could help with call centre issues where understanding regional or foreign accents was sometimes a problem.
