Do I even need to try to tell about the popularity of Facebook? However, regardless of the fact that Facebook is rising like is nobody’s business, General Motors seems to be of an opinion that paid advertisements on the famous social networking website are not doing it much good.

It may also be noted that Facebook will be soon putting up an Initial Public Offering and GM’s announcement comes soon before the former happens.
