Ad blocking 2015 global report: Ads are always annoying, no matter how they are served or what form they take. We are sure that many of you cannot stand pop-ups that pop up while you are reading something on a website. 
So it will be very natural if most of you have installed ad blockers to avoid these types of ads.
According to Business Insider, ad blocking software installations are on the rise. A recent report from PageFair and Adobe revealed that ad blockers have seen a 41% increase in installations since last year, which also means there are a lot of advertising companies that could potentially lose out.
In fact, the report claims that Ad blocking has cost publishers an estimated $21.8 billion in 2015!
Forecasts even say that in 2016, this amount is expected to almost double to $41.4 billion.
This is of course not surprising, thanks to the efforts of services like the EFF who recently released an extension that prevents spying by advertisers.
Apple's iOS 9 also has a feature in Safari that could block ads as well.
It should be noted that two months ago, Google's Larry Page admitted that ads could be better served in a way that would annoy users.
Maybe this is the next thing all advertisers should think about.
