January 30, 2007 With Windows Vista becoming broadly available this week, we suspect that one of the access it provides to XM Radio Online as part of its digital music hub will see a huge boost in the popularity of the medium, and indeed, could be the making of a significant new player on the global media landscape. XM Radio Online delivers more than 80 radio channels of commercial-free music. Web users can sign up for a free, three-day trial of XM Radio Online and unlimited listening is available for US$7.99 a month. Those who subscribe to XM Satellite Radio for the car, home, or portable listening can enjoy XM Radio Online for no additional charge.
