What are the most profitable online affiliate programs or fields?

I current have spent the last 4 years advertising dialup internet access through online ads. I want to expand my business into new areas and fields. ISPs have treated me very well over the years. I'm positive there are other lucrative fields besides dialup and dsl to market online. I'm looking for comission based pay per signup like programs. Or different fields to consider. ANY advice would be helpful.

You may want to look into credit card affiliate programs. From what I have read they can be quite lucrative.

There are TONS of affiliate programs and many ways to promote them. There is no such thing as "getting rich quick" but if you are willing to put in the time and effort, the rewards are great. You need to have a website, a product, and a way to promote or get traffic to your site. Article marketing or blogging is the most popular way to do this (no cost).

This call Yuwie great for business and comission and pay there.
