From ABC News via Dave Hughes at DCRTV, it’s being reported that the XM and Sirius satellite-radio services are to announce a merger today.

It’s long-expected move, but still unanswered are any questions about what will happen to XM’s D.C. operations, out of a converted warehouse near the intersection to New York and Florida Avenues NE. (Wonder if the rat problem complicated the deal at all.)

Sirius, FWIW, broadcasts out of Rockefeller Center in New York, and it would make sense on some level, you would think, for a merged satellite-radio giant to consolidate broadcast facilities in one place. I’d think there’d be more room for growth and it would be more economical in D.C., but NYC is still the center of the broadcasting universe.

Hey, XMers—-if you’ve heard anything, let City Desk know. Discretion guaranteed.

UPDATE (5:17 p.m.): From the Post write-up:

“The commitment of the company is to have a significant, presence both in Washington D.C. and in New York City,” said Hugh Panero, currently chief executive of XM Satellite Radio.

No decision has been made on the eventual name of the company or on the location of the headquarters. Both subscriptions will be honored and then they will eventually be combined, the company said.
