I would guess this is the ever increasing paid presence on the search screen. Take a look at a screenshot from 10 years ago. Today on a smaller screen you can't even see organic results. With some shopping and maps results you don't get much organic on a larger screen. I find it amazing this is not more discussed as losing value as organic search. As a marketer I see this often forces a company to often bid for their brand name searches as competitors will hog the screen if you don't. It will be interesting to see how it develops further but I can't see Google doing anything but owning search ongoing for the short to medium term.
