A letter floating around on Google+ seems to show NBC Universal officials threatening suppliers to support SOPA — or else.

We are writing to ask you for help on an issue that is one our top business priorities – content theft on the Internet, which is a major threat to the strength of our business. Our major guilds and unions are joining us in the fight to keep our businesses strong so that the tidal wave of content theft does not kill jobs. But if the current trend continues, it’s not too strong to say that this threat could adversely affect our business relationship with you.

Thanks to Google+ user Emmett Lollis for putting it up. We’re looking to see if we can find any other details about the letter and confirm it’s real. The letter seems focused on entertainment content over news content. EDIT: The letter’s original source appears to be an anonymous comment on TorrentFreak. Phone numbers are listed on the letter; will offer up more info as we get.

Second update: Some checks on names; Phil Tahtakran is listed as a lobbyist for Comcast and General Electric, who together own NBC Universal. John McCay’s public LinkedIn profile shows that he is the “Vice President, Corporate Communications at NBC Universal.” Called both numbers listed, and they led to voicemails for each person.

Third update: NBC Universal does use outside suppliers and they do have their own online portal.

Fourth update: Via Google+ user Occupy Updates, here’s an e-mail thread involving McCay and others attempting to launch an anti-piracy campaign last year. TechDirt did the dirty work on this one, including filing a FOIA request.
