Ad-blockers have been around for decades. They create a much better reading experience (shhh, TechRadar is listening!–Ed) as you’re not constantly bombarded by visual junk, autoplaying videos and mysterious sounds emanating from one of your 72 open tabs.
Although it may appear otherwise, adverts are not actually on the site you visit in your browser. The website provides a basic HTML document that contains instructions for formatting, locations from which to retrieve images, and how to fetch and display other resources. Adverts are one such resource and are pulled from a remote location on the server of an advertising company.
The URLs of these ad servers are generally well known and have been compiled into dozens of lists that can be downloaded by you or your PC.
