It&'s been less than one month since Facebook launched its new deals service on top of its still-nascent Places platform. But that hasn&'t stopped it from lining up some of the US&'s biggest brands in time for the holiday season. A few minutes ago, the social network posted a note that shows just how many companies have already climbed on board to offer deals over the holidays. Note that some of these have already been announced (including the charitable Southwest Deal that donates $1 per check-in to the Make-a-Wish Foundation), but seeing them in one place makes it easier to gauge how much traction the feature is getting.

So why is this important As we&'ve discussed before, these location services are in a race to snap up deals with as many national brands as possible, in addition to the longtail of local businesses. Some of these brands want exclusivity (they don&'t want to be on the same location service as a competitor), and brands will probably work with one or two location services instead of taking a shotgun approach so as to minimize shopper confusion. And many people are just trying out location apps for the first time �a4���a4� if they start associating deals with Facebook (or Foursquare or SCVNGR or Gowalla) then that might the app they turn to first in the future.

Of course, Facebook isn&'t the only service with big brands on board. Foursquare is currently doing some very interesting things, with Safeway and Pepsi, and had plenty of deals lined up with national brands for Black Friday today, with offers from the likes of Toys R Us and RadioShack. And SCVNGR recently signed up Coca Cola for a big holiday promotion.
