I’m still trying to figure out if last night’s 30 Rock was a little bit of corporate-sanctioned self-parody or a genuine dig at NBC-Universal’s overwhelming “Green is Universal” campaign that completely took over this week’s programming on all of the company’s networks.

In case you didn’t catch it, 30 Rock’s fake-NBC was having a green week of its own: an opportunity to look good to the public, solidify branding and get people to buy GE products. Sound familiar? Other than the awkward, 80s-nostalgic PSAs of Sylar planting trees in Rockefeller Plaza, NBC’s efforts have come across more stunty than anything. “Green” is one of those 21^st century buzzterms like “blog” and “meme” that makes PR ladies foam at the mouth. Just saying it (or coloring your logo) brings in tons of attention and publicity. So while I’m sure NBC has probably done a lot of good with their initiative (and Al Gore’s presence certainly lends them some cred), I’ve spent the bulk of this week questioning their sincerity.

At least the green didn’t make 30 Rock any less awesome (they definitely pulled the theme off more successfully than Scrubs). I just wish they’d tone down the “high profile” guest stars this season. David Schwimmer showed up as Greenzo, fake-NBC’s green spokesperson, and reminded us all why he really didn’t have a career after Friends. His character did prompt this gem of a quote from Jack though: “Look how Greenzo is testing. All the demographics love him: colored people, broads, fairies, commies… Gosh, we gotta update these forms.”

All of these guest stars have me worried that NBC doesn’t have as much faith in 30 Rock as they should. Their ratings are up from last season, so I think it’s time they drop the cameos and let the hilarity speak for itself.
