The world’s largest social network has raised more than $16bn (£10bn) from investors, only just behind the $18.1bn raised by General Motors in 2010 and Visa’s $17.9bn IPO in 2008.

Facebook’s share price values the firm at $104bn (£66bn), more than many other global blue chip companies such as McDonald’s, Kraft and Disney.

In the first quarter of 2012 Facebook reported $1.06bn (£657m) in revenue, down 6.5% quarter-on-quarter, although still up 45% year-on-year. Profit dropped 12% year-on-year to $205m (£127m).

Advertising revenue accounts for 82% of Facebook’s total income, but advertisers have recently cast doubt on the social network’s ability to act as a revenue driver for them.

US car giant General Motors said it was pulling all paid for advertising from the network earlier this week.

UK marketers from various sectors have told Marketing Week that Facebook must provide them with more proof their campaigns on the network provide a return on investment if it is to secure their advertising budgets in the future.
