Apple is on a roll as 2013 winds down. Just one week after Apple confirmed that it acquired Israel-based Kinect inventor PrimeSense, the company has acknowledged another small buy. The Wall Street Journal on Monday reported that Apple has acquired Topsy, which bills itself as a social monitoring and analytics company. Topsy wouldn’t comment on the deal but WSJ managed to get a nod from Apple. “Apple buys smaller technology companies from time to time, and we generally do not discuss our purpose or plans,” an Apple spokesperson told the paper after confirming that it did in fact acquire Topsy. Apple paid more than $200 million for Topsy according to The Journal’s report, but the newspaper’s sources don’t know how plans to use the firm’s technology moving forward.
