I subscribed to the radio only feed for several years. Partly this was due to the quality of the TV feed as observed on periodic free games from MLBTV. Also, living in the Memphis area, I was blacked out for games involving the Reds, Braves, and Cardinals. I was not going to pay full price for a limited product. By the way, non of those blacked out games were on TV in my local market. Once I got to Texas and saw the quality of the MLBTV product, I have paid tor that package for the last ten or so years. I watch several Phillies games each week and generally have been satisfied with the product. These YouTube broadcasts just don't measure up. Don't know why, but it was certainly a disappointment. So I jumped over to the radio feed which is also included in the package I buy each season.
Thinking back to sitting in my car to try to get a radio signal from Philla (in Tennessee and up state New York) or the time when I was well out of range of the radio, I sure would have loved the radio package now available world wide.
