Are there laws preventing advertising of guns on TV?

[k9870]

I never see gun companies running ads on TV. Even on shows about hunting or shooting. You expect that during top shot or the IDPA nationals or something youd see smith and wesson or reminmgton, one of the big names would be running an ad or two. I know that the anti tobacco people made it illegal to run cigarette ads on tv, wondering if the anti gunners did the same or if gun companies just dont want to air ads?
