my e-m to viacom:
'Dan Rather is causing trouble enough for your companies, and before people start dumping your stock, I would have CBS make a less arrogant and biased statement about the evidence. Perhaps you could do a story about WHO provided the memo and become great journalists again?'

My gut feeling is the Sumner Redstone has become a spiteful nasty old bird. He has interests in many organisations which are content to undo American culture. At this point in his life he would be happy to have Viacom tank if it meant getting Kerry elected.
The sponsors are the weak link in their chain.
I would also suggest going after CBS football sponsors. They generate a ton of revenue for CBS. All you have to do is switch brands. If it's a Budweiser commercial buy Corona or some other brand of beer. And let them know it.
