Google holds a lot of live events. Some are pretty major, like Android and app announcements. Others are a bit more basic, but still just as interesting, like Office Hours for example. With all the different live broadcasts coming out of Google's camp, it's almost impossible to keep up with everything, though. Correction: it was almost impossible to keep up.
Now, Google has launched Google Developers Live, a place to keep up with all of El Goog's broadcasts in one place.
