Ripit writes "Just yesterday the Justice Department approved the merger of Sirius Satellite Radio and XM Radio, a Sirius takeover to the tune of $5 billion. The transaction was approved without conditions, despite opposition from consumer groups and an intense lobbying campaign by the land-based radio industry. 'In explaining the decision, Justice officials said the options beyond satellite radio -- digital recordings, high-definition radio, Web radio -- mean that XM and Sirius could merge without diminishing competition. "There are other alternatives out there," Assistant Attorney General Thomas O. Barnett said in a conference call. "We just simply found that the evidence didn't indicate that it would harm consumers."'"
