theEweekly Wrap: Gagging, targeting and tracking

Super-injunctions crack The row over super-injunctions escalated this week as a Twitter account appeared to reveal the big names involved. @InjunctionSuper was set up on 8 May 2011, and sent just six tweets. Despite certain celebrities mentioned in the tweets denying any truth in them, the account amassed over 106,000 followers in four days. On Monday, there was a 14 per cent rise in visits to Twitter from the UK.

Wikipedia founder Jimmy Wales also joined the debate on Thursday. Pages for the celebrities in question had to be locked to prevent users from sharing the gossip. However, Wales said the only reason for this is that the information does not come from a 'reliable source' – if the names were to be published in a newspaper from outside the UK, they could be added to Wikipedia.

iP-Ads Google has been toppled from its position as world's top brand - by Apple. After four years at the top of the annual Millward Brown BrandZ survey, Google was knocked into second place with a worth of $111.5 billion (£68.5bn), compared to Apple's $153.3bn (£94.2bn), which is an 84 per cent rise on 2010. The change in fortunes is partly due to Apple's impressive sales of the iPad, and the launch of the iPad 2 in March.

This week, Google itself recognised the expanding tablet market with a new AdWords feature. Users can now target their PPC ads to tablet devices, separately to smartphones and computers, and can refine their targeted device by OS. Only standard text and image ads will work at the moment, and Google advised that users ensure landing pages work on tablet devices.

Digital police London's Metropolitan police have invested in software called Geotime, which is currently used by the US military. According to the Guardian, the programme can "collate information gathered from social networking sites, satellite navigation equipment, mobile phones, financial transactions and IP network logs", to map an individual's movements through space and time. A spokesman said, "We have used dummy data to look at how the software works and have explored how we could use it to examine police vehicle movements, crime patterns and telephone investigations."

Meanwhile, a pair of surveys have revealed that social check-in services are not yet truly taking off, due to security concerns. A report by youth marketing agency Dubit revealed that 48 per cent of UK teens have never heard of Facebook Places, Foursquare, SCVNGR or Gowalla. Of those who had heard of the geotagging apps, 45 per cent felt they were 'unsafe'. Another study commissioned by digital agency Beyond revealed just 17 per cent of the mobile population is using these programmes, with 48 per cent of those who don't citing privacy concerns.
