Welcome to this morning's edition of "First To Know," a series in which we keep you in the know on what's happening in the digital world.
Today, we're looking at three particularly interesting stories. Yahoo has partnered with Google for contextual advertising — but you probably won’t notice much. What you will notice, is a change in Twitter's mobile apps, where Tweets, activity, trends and suggested follows are now condensed down into one big discover tab. Finally, Facebook’s Developers Live debuted Wednesday.
It’s a video channel that will host walkthroughs, keynotes and other content for Facebook app developers.
Check out the video above for more on these stories.
