Facebook revises mobile messaging app Facebook on Tuesday released a new version of its mobile messaging app, a move that shows the Menlo Park company is trying to extend its reach beyond its already massive social network. The new Android version of the Messenger app doesn't require a user to sign up for a Facebook account, an interesting twist for a company that has been pushing to connect every human activity - from reading a newspaper story to buying a gift - into its social network. Product director Peter Deng, who announced the news at a tech conference in Paris, said the app was "a natural extension" of Facebook's overall mission to connect the world. Uphill climbFacebook released the app a day after the 20th anniversary of the first-ever SMS text, "Merry Christmas," sent by a British engineer to the mobile phone of a friend. Jordan Gray, who advises clients of digital marketing agency Organic about the latest technologies, views Facebook's move as a reaction to the activity in the market, "more so than trying to think ahead."
