Being a huge Yankees fan and living out of market like I do I recently purchased the MLB.com TV package so I can watch the games on the Internet. They sued to use Real video streaming however I cranked up the video tonight and noticed some changes form last year. After a quick check, yep, its using Silverlight! I'm sure this was announced somewhere along the way and I just purely missed it. But how cool is it that MLB.com is using Silverlight!
Yes, I spray painted some logos in the image :) to protect, well, myself!
Notice the media controls at the bottom of the video. These appear when you hover over the video.
