Website registration outfit Go Daddy paid NBC a couple million bucks to run a spot on last February's Super Bowl. Now NBC and owner-to-be Comcast are returning the favor.

Comcast Corp. and General Electric Co. this week unveiled a website, nbcutransaction.com, to explain Comcast's planned purchase of a 51% stake in GE's NBC Universal.

The site was registered by an entity called Domains by Proxy through domain registrar GoDaddy.com on Nov. 12 while the companies were still negotiating a deal.

Domains by Proxy is a GoDaddy.com affiliate that allows people or companies to register websites anonymously. ("Your identity is nobody's business but ours," the Domains by Proxy website says.)

Just who at Comcast, GE or NBCU actually registered this site? That's not clear, though the "Forward-Looking Statement" legalese that appears when you open the website implies the site is controlled by Comcast.

So it could be Comcast optimistically registered the site in anticipation of a deal. If so, at least Comcast supported an NBC advertiser.
