The version of Norton antivirus software that I use allows me to block banner ads on most websites. It also gives me the option of allowing some, but I have not taken the time to figure that out. I had originally blocked all banners, and thought many web pages looked more attractive and simpler without the banners.
Recently, I unblocked them to see what I was missing. Yes, there were a couple of banners that caught my eye, and I was intrigued by some of the interactive functionalities provided in some of the banners.
But.....I have now switched back to blocking. Yes, I realize I am undermining some of the web revenue model, but I found most of the banners to be irrelevant, too distracting, taking more time to load when I access the sites where the banners appear, and generally not worth it.
Why would anyone want to see all those ads unless for others, the ads turn out to be either of direct interest or simply entertaining?
