Number of ads does not necessarily scale linearly to amount of income. If the ads alienate viewers, then they become worth less. I know I personally watch less when they started sometimes subjecting me to 30 seconds of unskippable ads to watch a 90 second video. Recently, I hit “skip ad” and it took me to another ad, which made me less likely. The other day whole watching a video someone told me to watch, I paused to look at some text. After a few moments it started rolling an ad while I was trying to read the text. The more this happens, the less likely I am to watch. Wild be interesting to know statistics on viewership versus more obnoxious ad behavior, but there’s likely at least some decline in per ad avenue versus number of ads crammed in the face of viewers.
It’s a fair point. The honest answer might be that with current technology there is simply no way to make Youtube profitable. If Google can’t pull this off I don’t think anyone can. In which case we will see a slow, but profitable death for Youtube as they make increasingly user-hostile moves, like raising prices, increasing ads, and eventually becoming increasing aggressive about deleting rarely watched videos. This will kill their user base over time of course, but they are still sitting on a massive treasure trove of content. The one thing in their favor is that storing and transmitting data gets cheaper every year. Maybe that’s what they’re holding out for.
