theEweekly Wrap: Dorsey returns, and Microsoft complains

By Rachel Hand topicIcon Manchester
EU'll be sorry Microsoft is to lodge a formal complaint with the European Commission about what it judges to be Google's anti-competitive behaviour. They accuse the search engine market leader of using technical measures to restrict Bing's ability to index websites, and of blocking YouTube on Microsoft smartphones, among other grievances.

In other news, Google has agreed to an investigation by the US Federal Trade Commission over privacy flaws in the Google Buzz network. Google has already been investigated for data collection by Street View cars; on the other hand, a Google operation known as the Bing sting seemed to prove that the Microsoft search engine was copying Google's results.

Prodigal founder Twitter co-founder Jack Dorsey has returned to the helm this week after a few years in the back seat. Dorsey sent the first ever tweet five years ago, and in the meantime has set up mobile payment company Square. However, this week it was announced that as well as remaining CEO of Square, he will be working day-to-day as executive chairman at Twitter.

Dorsey told the Wall Street Journal that "mainstream relevancy is still a challenge" for Twitter; earlier this month, head of API Ryan Sarver discouraged third party developers from building any more platforms in an attempt to move towards a more consistent user experience.

Tailored TV Sky has written to customers advising them their information will be used to create targeted adverts on Sky Player, BSkyB's on-demand viewing platform. A new system called Sky AdSmart will use details such as postcode and previous viewing choices to determine which adverts will play, as well as which programmes are recommended to them. Although this service has been provided online since 2010, according to tailored ads will now be rolling out to Sky+ boxes.

However, May will see the introduction of the e-Privacy Directive, which will require brands to get consent from web users before using browser cookies. The cookies, which track the user's movements, enable targeted advertising similar to the ones promised by Sky. The Sky Player website explains that users can opt out of tailored ads if they would prefer.
