Facebook, trudging through its awkward teenage years, is turning 15 on Monday. Launched in 2004 as “The Facebook,” the service was originally intended only for Harvard students. It’s now a massive global business that connects some 2.3 billion users. It was born in an era of desktop computers, years before the iPhone, and ran no ads. At the time it was impossible to imagine that someday countries like Russia and Iran would try to use it for sophisticated information operations in order to influence elections around the world.
