1. Coca-Cola has launched a TV ad featuring Mark Ronson and Katy B as part of its Move to the Beat campaign to support its London 2012 Olympic sponsorship. The Move to the Beat campaign has been developed to bring teens closer to the Olympic and Paralympic Games by fusing music and sport. It includes a TV ad and Facebook app, as well as a 30-minute documentary starring Ronson. Coke has also created a 25m “Beat Wall”, painted by young urban artists in London’s Hackney.

2. VisitBritain has signed up Victoria Beckham to its 'Great' marketing campaign, which draws attention to the nation's rich fashion heritage in an attempt to increase visitor spend in Britain by £2.3bn over the next four years. Beckham's involvement in the campaign was unveiled at the launch of a 'Great' branded subway train at New York's Grand Central Station as part of New York Fashion Week.

3. Twitter will be the de facto news service at the London Olympics. Engine convened a conference at its London head office to discuss issues around social media. Topics covered included sponsors' use of social media, Twitter tips for athletes, and Locog's role in helping brands communicate with consumers online. The panel concluded that athletes should be encouraged to tweet during The Games, but any misuse of the network – such as disparaging other Olympians – would result in athletes losing their own credibility.

4. TV adspend remains healthy despite economy concerns. The TV advertising market is expected to be up by between 2-3 per cent in April, according to media agency sources. This increase could lead to a more impressive year-on-year rise of 4-6 per cent in May, media buyers said. April is expected to benefit from the presence of Easter and spending around the school holidays. Meanwhile, brands seeking to avoid the Uefa Euro 2012 football tournament, as well as those advertising in the run-up to the competition, are likely to up their investment in TV in May.

5. Coca-Cola is the biggest brand on Facebook, but Whole Foods is the biggest brand on Twitter according to a new piece of research by analytics firm Socialbakers. The research confirms what Socialbakers has already found previously, which is that for different social networks there’s a different dynamic to the way fans engage. Facebook is all massive global brands, while Twitter manages to get a few unusual names in the top 10, like T-shirt retailer Threadless. But where does that leave Google+? According to Socialbakers, in a pretty good place – it found that brands using the most recent social network were growing their fan bases faster than brands on Twitter, leaving us to ponder if it might one day take over the second place (it’s still a long way off though, and a really really long way off catching up to Facebook).
