Twitter to make stock market debut

Twitter has unsealed the documents for its planned initial public offering (IPO) of stock and says it hopes to raise up to $1bn (€738m).

The company is also disclosing that it generated $317m (€234m) 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 compares with Facebook’s nearly 1.2 billion and LinkedIn’s 240 million.
