and this is how links used to look like back then... http://hop.clickbank.net/hop.cgi?AFFILIATE/SELLER
You can even see the marketplace. it's very interesting.
This is a sales page I found on the marketplace: Submit 3000 (very shorter that today's pages)
And this is another sales page: "Chicago Man Reveals Web Marketing Secrets!" the domain is www.wso.net it is probably the first WSO ever. "Chicago Man Reveals Web Marketing Secrets - Backs Up Offer With Money Back Guarantee" says in the title.
I also noticed commisions used to be 20-50%.
