audience that is more likely to have ad blocker or skip ads which then lower the money you'll get per million views. $1200 is great but would probably trend towards and older demographic (more likely to view ads) with better targeted ads (which lead to higher revenue). For example someone with a million subscribers about home improvement would make more than an average musician because the home improvement viewers will probably watch the Home Depot ad. More views, targeted ads, high revenue. Studio C doesn't have the benefit of either of those.
