I doubt that the advertising revenue is that notable.
However, I do occasionally disable and click a few. Makes more sense to me as most ads return more revenue for clicks, rather than traffic exposure.
But they are still getting out of hand. As mentioned, many browse on older gear which is simply not capable of handling all the crap that gets wedged into many sites these days.
Anyway, I occasionally buy an actual paper copy of STW. It has a special place in my heart as I may have been in the very first issue!
Edit. Might have been the second issue actually. Met Chipps and a photographer up on t’moors many years ago and posed for a pic holding the mag :-)
