I've read many great business and technologies ideas on this site. But before you start your business you should think about advertisement to have success in your business.
There are many ways to advertise your products or new technologies. You can advertise via TV, radio, Internet, newspapers, different posters, and many, many other ways.
Usually it takes too much money.

So, I offer a new kind of advertisement and I hope it will be cheaper to use for your business. My idea is a kind of crazy, but it is a very good and new idea. I offer to put your advertisement on the back of big dogs. Let's explain. I offer to produce T-shirts for dogs. On T-shirts you can put words, pictures concerning your products or new technologies.

For e.g. I have just read on this site an idea to create nappies for dogs. If you are going to start this business you can advertise them on T-shirts for dogs.

I am sure it is a great deal and it will work.
