My affiliate program of choice is Strong Future International (SFI). I have been amazed at the growth that has happened over the 14 years that I have been an Affiliate.
SFI was formed and begin business in 1998. That was the same year that Google started. Did you know that Facebook began in 2004? Internet companies that stand the test of time show with their longevity that they have experience and can grow with the times. None of the companies that I mentioned look like or are the same business they were when they started. They indeed got better.
If you are looking for a tried and true online business, look for such a company.
