I'm still seeing things as I have for some time: also boughts, then sponsoring products, then much further down the page, another sponsored products carousel.
Seriously, how many ads does Amazon think people will look at on any one page? Is anyone going to click through 23 pages of ads on the first carousel, then go down and click through 61 pages of ads on the second carousel? I can't imagine that happening very often.
We have determined that we’ll be able to fill 80% of the user’s display with advertising before inducing seizures.

Fun fact: long before RPO, a similar idea appeared in the short-lived Sci-Fi TV series,
Max Headroom. In the first episode, an evil corporation, whose name I've forgotten, introduces blipverts, a new form of advertising intended to bombard a viewer with information so fast that it would be absorbed by the subconscious without conscious filtering. The only downside was that it caused some people to explode.
