Pocket, the popular DVR-like service that allows readers to save web articles and videos to enjoy later in the browser, or in apps for iOS, Android, and the Mac, has announced a new service -- for publishers. Following up on a recent Pocket blog that showed how long stories could live on inside Pocket's system -- far longer than they might otherwise stay in the spotlight on the web. That's similar to how a recorded TV episode might get watched more often, and over a longer time period, than it's original TV schedule would allow. Pocket was interested in seeing how much more often, over what exact periods, and other data. And they figured publishers might be as well.
