I started earlier though. I think my first sponsor was via PennyWeb(?).
But... the early days were cool.
Sponsors like Cyberthrill Casino were paying .25 flat per unique. Conversion didn't matter and shaving wasn't invented yet. Made tons with them for more than a year.
Suddenly they stopped paying everyone.
Didn't matter what you emailed, they placed this auto reply on their support mailbox:

Our Final Response
------------------
If you have not received a check within two weeks of the date that
the check was sent on, please stop advertising for us.
We have a sophisticated tracking and fraud control system.
The traffic you sent us has been continuously monitored.
It did not meet the required pay back criteria for this program.
Your account has been banned automatically and you will not be
paid for your past hits. Our decision on this matter is final -
please do not send any more inquiries about previous checks.
We admit that we should have informed you of this decision in advance.
However, due to the large number of advertisers and the large volume
of fraudulent activity, it takes a few weeks to gather full statistics
on each account.
Finally, if you would like a more personal advertising support,
you may contact "Cash For Clicks" at www.cashforclicks.com,
an independent agency that does advertising for us.
Thank you,
