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.
