Ever since I watched my first Olympics (that I remember) in Sarajevo (in '84), I've been hooked. In fact, my plan was to be in the 1992 Olympics in Track & Field :-).
That didn't come to pass, but I can at least become an Olympics junkie when they're on TV. To help you keep track of the coverage, there are 2 FREE Olympics apps available for iPhone/iPad and Droid devices.
The NBC Olympics app has live updates on every event from London. Check out NBC Olympics news, results & schedules, TV & Online listings, medal counts, video, photos, and much more. Or, if you need ever more, you can download the NBC Olympics “Live Extra” app which has live coverage of all the Olympic Events. Unfortunately, I can't use this app since you do need to enter your information for your paid TV account (which we don't have).
If you don't have cable like us, never fear, since NBC has extensive coverage on the network NBC station, in addition to the multitude of cable stations.
