Any ideas and experience with standing up against juggernauts are welcome here. The problem that leads me to start this board is specifically about broadcast media, but that problem is not the only one that exists.
If you have a problem with a company that is headquartered in New York, the number there for inforrmation is (212) 555-1212. This is the US, so it is important to "follow the money" when you want to have influence. I would suggest a single comment on their comment line or whatever it is called. Be respectful, state what action they have taken that troubles you, and state what action you will be taking. State what action the corporation could take to repair the damage they have done, to any individuals, to their customers, to our world-view.
Then figure out who the customers of the company are, and contact them. Be respectful. Be honest. It is okay if you are a little emotional, this is an emotional issue, but don't get mad. Get it done!
Interaction with the internal comment structure (like message boards) is a bit counterproductive. Contacting media outlets external to the company would be more useful. Word of mouth, phone calls, e-mail, letters to your local paper and radio and TV stations. Remember to contact the local outlet and that outlet's parent corporation. And share your successes. I'm not finished with this.
