An example of this is: Video Professor He markets DVDs that teach you how to use eBay, Word, etc. He talks about them, screenshots, etc. If I wanted to launch a product where I talk about eBay, Adwords, etc, how do I go about legality? Do I have to have prior written consent from the companies to talk about them, or what? How do I go about doing it without getting sued. They could sue since youre using their trademark for the production of your product. (By the way, I cant believe how many products on clickbank have the google named attached to them, How are they not getting sued?) Crazy... Anyways, thanks!
