Way before Facebook bought Instagram for $1 billion, Twitter apparently made an offering of its own, to which Instagram initially agreed to.

The offer from Twitter, according to The New York Times, was for $525 million. Instagram's CEO, Kevin Systrom, agreed to the buy-out, but changed his mind before selling Instagram to Facebook without allowing Twitter to make a counter offer.

What's interesting is that Systrom had stated while under oath to the California Corporations Department that Instagram had never received another formal offer. None of the parties have commented on the Times article that brought this information to life, but it could mean we might be in the throes of an intense legal battle shortly.
