Trying to start a new product is tough
If you want to make money in golf, look for the next big thing where there is
one major provider of a new product with a patent pending
major provider has a large advertising budget
has some competitors selling knock-off products
Start marketing the knock-offs heavily, leveraging the main products advertising against it. If you know much about Internet and search engine marketing, then the lightbulb is probably turning on. If not, you can still do well with offline (direct mail and publication ads), just the feedback loops on your testing will be much longer.
