While the day has been coming for a long time, last month was the first time that mobile overtook desktop in total worldwide Internet usage, says analytics company StatCounter.

After launching Skype for Web worldwide back in June, today the previously chat-only web app is adding support for making phone calls and other new features.

Yahoo today announced that it’s revamping the way it aggregates news content and in the process launching redesigned commenting, news discovery, and notification features to users on Android, iOS, and through its Yahoo homepage on the web.

One of the many things Facebook does well is make it nearly impossible to miss when one of your friends turns another year older. On the web, birthday reminders are placed prominently near the top right with links to easily wish your pal a happy birthday, and on mobile Facebook has experimented with alerts and other ways to help you not forget someone’s big day.

Now Facebook appears to be testing an even more personal way to make your birthday wish stand out: video messages. The Next Web reports that some mobile users have seen a new ‘birthday video’ option appear under Facebook’s Birthdays section (although don’t worry if you don’t see it yet, I don’t have it either).

Google announced today that it’s releasing mobile apps for its Google Classroom service for both Android and iOS devices. The company officially launched Classroom to its Apps for Education customers in the US during the summer offering them a web-based platform for planning lessons, handing out assignments, and working alongside students. Teachers and students will now be able to access those features from mobile devices through the new apps and Google is also adding a could of new features to the platform.

In addition to a new teacher assignments page and archiving functions for Classroom, Google notes that the mobile apps will let users snap a photo to share or attach to assignments, share content from other apps, and access content cached for offline viewing.

Snap a photo: Right from the assignment page in the mobile app, students can snap a photo and attach it to their assignment — whether it’s the experiment they just did for a science class, or a drawing they made of their family tree. And if they’ve forgotten their homework, they can ask someone at home to snap a photo, text it and then turn it in with the app. Of course, if the dog has actually eaten it, Classroom can’t help you.

The new Google Classroom apps are available on Google Play and the App Store now as well as on the Google Play for Education store.
