Another problem is that you are forced to watch the same video again and again.
Yesterday I was visiting a friend and I saw the WatchDogs commercial on youtube (the guy selling phones to people with a special app etc)
Was the first time in ages I a saw a commercial on youtube and I watched all of it because it was quite a great commercial unlike the other 99%. The problem was 2 videos later it got annoying.
Neither consumers not game publishers are helped when the commercials get annoying.
