Since XM radio has very little commercials now, I often wonder how long it will be before we start hearing full sets of commercials that last 3-5 minutes? It seems like history has shown that these types of services always start inserting more and more commercials over time. Just look at cable and satellite TV. I still can't believe I'm paying close to $50 a month for my Dish and still have to skip through 17 minutes of commercials an hour. I just hope XM radio doesn't follow the same path because if they do, I will end up going back to local radio.
