Mobile messaging startup Snapchat has reportedly rejected an acquisition offer from Facebook that would have valued the company at more than $3bn (£1.8bn). The app was launched in September 2011 and according to its website, at least 200 million snap chats are sent every day. The report of Facebook's interest in Snapchat comes a couple of weeks after the world's number one internet social network acknowledged it was seeing a decline in daily use by teenagers in the US.
