When CBS changed its no-advocacy-ad policy to accept Focus on the Family’s Super Bowl ad, the Tiffany network opened up a family-size can of worms.
Flatworm A (via Alternet):
CBS Corporation Bans Ad Calling for Marijuana Legalization Over ‘Morals’
The fifteen-second ad, asserting that taxing and regulating the adult use and sale of marijuana would raise ‘billions of dollars in national revenue,’ was rejected out of hand
The ad, sponsored by the National Organization for the Reform of Marijuana Laws (NORML), would have appeared on CBS’s 42nd Street digital billboard beginning the first of February:
Accepting ads (however understated) from an anti-abortion group while rejecting ads from a pro-marijuana outfit is not only inconsistent, it’s bad business.
Here’s guessing the worm will turn on CBS, and soon.

“Here’s guessing the worm will turn on CBS, and soon.”
I agree with your sentiment, but I just don’t get what the downside for CBS is here. It’s CBS’s airtime; it’s CBS’s billboard; what’s wrong with CBS deciding what it hosts thereon? And what will be the negative consequence of their decision?
Getting your ad rejected by CBS is already a marketing tactic (hello, news coverage), but now it threatens to become a political tactic as well. Once CBS becomes the wishbone in the push-and-pull of ideological battles, I think it might find the revenue those ads it does accept brings in won’t be worth the cost to its public image.
OK. You’re probably right (having a better vantage). Maybe I’m cynical, but I already think CBS’s (and all the networks’) images are already tarnished. Fox News is more “trusted” than any – what does this say about CBS’s “image”?
In fact, perhaps the folks at CBS think that a naked pander to the right is the way to GAIN image points.
Wouldn’t surprise me, Steve. Then again, very little does these days.
Without all the noise about the FoF/Tebow commercial beforehand, most viewers would have been left wondering what the heck it was about, a not uncommon impression with Super Bowl advertising.
