Adblocking is a problem created, in big part, by YouTube. I used to watch YouTube on the IPad app and I would get 5-10 second ads at the beginning of the video every now and then. That was ok but, at some point, I started getting two or three videos that I could not skip and then I got a Colgate ad that would appear everytime on and on and then I started getting the Colgate ads in the middle of the video... It all just became too much so I tried signing up for YouTube plus (or whatever it's called) but it was not available in my country. You know where this is going.
