Apple has shut down the Twitter analytics company Topsy two years after it was acquired.
Topsy is (or was) a company that analysed raw data from Twitter to help gauge public opinion. It had rare access to the Twitter's unfiltered data stream.
We reported on Apple's acquisition of Topsy for around £122 million on December 3, 2013, making it one of Apple's more expensive purchases. Now it's been confirmed that Apple is shutting the service down.
Topsy's Twitter profile also reads: "Every tweet ever published. Previously at your fingertips."

It's still not entirely clear what Apple has used Topsy for, though the above redirect suggests that its technology can be found in iOS 9's powerful search function. This Google Now-like feature proactively seeks out services you might need based on context, and places this alongside data sourced from the internet.
There's also a chance that Topsy's technology has been put to use behind the scenes of Apple Music and Beats 1.
