We've searched our last tweet. — Topsy (@Topsy) December 16, 2015
Topsy, a Twitter analytics company acquired by Apple in 2013, tweeted last night that the company has searched its last tweet, as Apple has shut down the service. Topsy’s website now redirects to an Apple page which shows how to use search in iOS 9, perhaps hinting at where Topsy’s technology was used most. Topsy was acquired by Apple for more than $200 million two years ago. The company was originally known for analyzing tweets and “the social web,” though how Apple used Topsy was never completely clear.
