Via communications with NFL spokesman Greg Aiello and another source who’ll remain nameless, we’ve learned that the no-live-blogging policy sent by the Cowboys to the media on Wednesday is not a new development, and that it applies to all NFL teams.

“It’s nothing new,” Aiello said via e-mail.  “Those are the same rules we have had in place for several years for those that receive credentialed access to NFL facilities.”

Per information provided by the unnamed source, the e-mail circulated by the Cowboys regarding online content for 2008 is merely a cut-and-paste of a memo that was disseminated on June 11 by the league office, which announced the 100-percent expansion of the former 45-second rule, and which summarized the league’s online content policy.

So, for accredited media, there can be no live blogging from the press box.  (We’ll keep that in mind if/when we ever get credentials to a game — and if we ever actually use them.)  There’s no indication that this policy applies to live-blogging from the basement.

The real news here is that media sources will now be able to post on the Internet up to 90 seconds per day of interviews, press conferences, and practice video.
