Review of 2013: what happened in the news in October

Technology topped the news agenda in October. The 14-character social media network Twitter announced its planned $1bn (618m) initial public offering (IPO).

Twitter said it generated $317m (£196m) in revenue in 2012 and that it had more than 218 million active users as of the end of June, up 44% from a year earlier. That compared with Facebook's nearly 1.2 billion and LinkedIn's 240 million.%VIRTUAL-SkimlinksPromo%
