How to Survive in Your Industry?

There are businesses where the best thing to do would be to squeeze your customers as much as possible for a brief perioof time in which you understand that you will not survive. You can also harm your industry to make it for the worse later. The one thing that worries me about that is, with the last ten years or whatever, people gave of these great, big, giant companies that conquered the world and everything u they make their money off advertising. They never figured out, they never had to figure business model, because they just said, let's let's get all the audience, and then later, well, we'll make it off advertising.
