Here’s an update to a story Brance discussed earlier this year - the proposed acquisition of XM Satellite Radio by Sirius Satellite Radio.

The Federal Communications Commission (FCC) has begun its 180 day review period, during which public comment on the possible effects of the merger are sought. Even prior to this review period, however, intense lobbying against the merger has been forthcoming, particularly from Clear Channel Communications and the National Association of Broadcasters.

Since both Sirius and XM feature lively, 24/7 bluegrass programming, many of our readers have been following this issue with interest. The planned merger would not immediately involve consolidation of services, and is not possible at this time due to incompatible technology. What might develop after the merger will surely be a focus of the FCC review.

Here are a few more stories on the start of the 180 review we found online for those who want more details.
