Juli Clover, MacRumors:

Apple last year acquired Laserlike, a machine learning startup located in Silicon Valley, reports The Information. Apple’s purchase of the four-year-old company was confirmed by an Apple spokesperson with a standard acquisition statement: “Apple buys smaller technology companies from time to time and we generally do not discuss our purpose or plans.”

And from the LaserLike web site:

We’ve built a web scale content search, discovery and personalization platform using advanced machine learning.

And:

Your interest search engine. Follow the topics you care about, with news, web, video, local, and more. Powerful content search brings you the full perspective in a feed you can control. Never miss what matters, with timely, relevant updates for your interests.

Keep this acquisition in mind as you watch the announcements on March 25th. This would certainly relate to the rumored news subscription service, potentially adding a significant level of personalization to a traditional news feed.
