WAY back in the early days of the graphics driven internet I used to use a filtering program called PROXIMITY to filter web sites for me. This was to change background colors, fonts, remove items to speed up page loading as I was on a dial up connection, etc., all strictly for my own viewing pleasure. Then X started their pop up/under cam campaign. I started filtering that out with Proximity. As ads became more prevalent I had to adjust the filtering more so my meager bandwidth wouldn't be overwhelmed When cable connections became available I continued to filter ads out as I was now able to do some serious multi-tasking. When Proximity's author dropped support for the program some of it's users banded together, created their own support network, and began writing filters for everyone to use. This worked great for a few years. I started using the Marathon browser a few years ago and found that I could accomplish the same filtering with that program. About that time FIrefox became available with plug-ins for ad-blocking.
Currently, I have an 8 MB/Sec internet connection and letting ads load is no longer much of a bandwidth issue. However, I've become quite comfy with nice, clean, ad-free pages that load F // A // S // T and use little memory. For this reason, I continue, and will always continue, to block all ads.
