Sirius to offer online-only service?

Soon people will be able to subscribe to an online-only version of Sirius radio, according to Siriusbackstage.com.

Sirius Internet Radio Plus would offer music and talk channels for about $12.95 a month. The channel listing would include Howard 100 and 101 (Howard Stern's Sirius channels), according to the Siriusbackstage.com report.

Sirius already offers online access for its current subscription customers, as well as a free three-day online trial to anyone who is interested. Channels choices are limited, however, for online trial listeners.

Sirius representatives were not immediately available for comment.
