Most companies are using less and less to no ads on YouTube MV now! I know it was never that serious to begin with but it seems more genuine reaching 1M/2M/3M views etc 
YouTube has cracked down on ads and filtering out.
It’s awkward too as I’ve noticed for example (won’t name any groups) some MVs have 10 times the views within a day but have less likes or engagement even after a few days than groups that have less views within a day but more likes and engagement.
Also now people can work it out easily by checking YouTube daily charts 
A group getting 20m views on their first day but not getting into the top 40 on YouTube daily vs a group getting 3M views first day and managing to get into top 10
We will probably start seeing new- all groups/ soloist getting less views than we’re used to as a result
