XM and Sirius together spent a total of $810,000 in the first half of 2007 to lobby the federal government, yet the NAB spent a total of $4.3 million during the same period, according to a disclosure form.

XM Satellite Radio spent $580,000, according to public records. Sirius Satellite Radio lobbying firms - the Paul Laxalt Group, Quinn Gillespie & Associates and Ricchetti Inc. - spent $230,000 total through separate filings. A fourth lobbyist, the Amani Group, has not filed a lobbying report yet.

The NAB, which represents roughly 7,000 radio stations, lobbied on various issues including the satellite radio merger, according to the Senate’s public records office. In addition to Congress, the NAB used the $4.3 million to lobby the FCC and the U.S. Patent & Trademark Office.

Under a 1995 law, lobbyists are required to disclose any activity that could influence executive and legislative branch members.
