French TV and radio Stations will be violating French law by telling people to follow them on Twitter or Facebook, media regulators say.

You cannot say 'look us up on Facebook' or 'Look us up on Twitter'. What we advise people to say is: 'Look us up on the social networks' -- because Facebook and Twitter are commercial brands, said CSA spokeswoman Christine Kelly. The “follow us” and “like us” can’t be used in French channels, as it amounts to advertising for those sites.

Media usage of mini-messaging via social networking sites has mushroomed with France's frenzied coverage of the arrest of former IMF chief Dominique Strauss-Kahn in New York on attempted rape charges, but the CSA media industry regulator is warning that such covert advertising is against the law.

Christine Kelly, a spokesperson for the CSA, tried to explain the decision by saying it “would be a distortion of competition” to “give preference to Facebook, which is worth billions of dollars, when there are many other social networks that are struggling for recognition.”
The channels can say 'find us in social networking sites' but can't mention the name of the service.
