On average, how many national satellite or cable channels does a company pay to have their add run?

First off satellite channels are cables channels just delivered via satellite.





There is no average, no magic number. It depends highly on the type of product or service your are advertising. Your question is really not a question.





Many ad campaigns don't even use cable TV, they might use network TV, magazines, radio, or newspapers. As you can see your question really doesn't make sense.
