Re: A concerted effort??
Rather than boycotting TV itself, why not pick a particular network, show, or group of shows within a given time block on that network, then let the sponsors know that you're boycotting the network / shows which advertise their products, and furthermore refuse to buy their products? It could be done on a rotating basis, one network one week, one the next, etc. - sort of like an electronic flash mob. Chances are it'd get someone's attention.
