Un livre blanc Q4 Web Systems : Public company use of social media for investor relations : Facebook
"This whitepaper specifically focuses on the Facebook platform, and it is still the case that many public companies still fail to view Facebook as a viable channel mainly due to the perception that it is used predominantly by a younger demographic. This continued misperception is curious given usage statistics from 2010 to the present. The average age of a Facebook user in 2010 was 38 years old 6 , and in terms of year over year user gains from 2010 to 2011, the highest growth area by far was in the Boomer segment (aged 50-64) 7 . A recent study shows that half of all American adults (or 65% of the online adult population) are using social networking sites such as Facebook, MySpace and LinkedIn 8 . And with an average user spending 23 minutes on every Facebook visit 9 , there are some very compelling reasons for companies to participate in the social media conversation."
