I don’t want to pay to access every site - especially those I visit only once.

Just eliminating the pop-up adverts would be enough

It will create a new internet business.

Aggregators, similar to Drudge but listing only sites, not articles.

Pay $10/month for package A, $20 for package B etc. And distribute the revenue to the sites based upon use and subscription.

Usage based Cable TV.

I realize that websites have to generate an income some way, but active pop-up ads infuriate visitors, and prompt them to utilize ad blocking software.

The easy solution is to simply embed passive ads on the page, and allow users the freedom to click on them or not.
