Google Play crossed a rather significant milestone this morning: something to the tune of 25 billion app downloads. While the accomplishment is weighty enough on its own -- especially given that the store also offers books, music and movies, which aren't included in this tally -- Google is celebrating in symbolic style with a number of apps and games for sale at just $0.25 over the next five days. Among the mix of discounted titles, you'll find publishers such as Gameloft, Electronic Arts, Rovio, Runtastic and Full Fat. Not to stop there, shoppers will also discover a curated collection of 25 must-own movies, 25 banned books, 25 albums that changed the world and 25 top-selling magazines.

With today's announcement, it was revealed that 675,000 apps and games now live in Google Play -- a healthy increase when compared to 600,000 titles and 20 billion installs just three months ago. As you might expect, Apple still claims the largest selection with 700,000 titles in its App Store, although with such a thin separation between the two, we may see Google Play eclipse its rival in short order.
