An interesting article about netflix and binge watching from 2017 stated that the biggest competition netflix faces was sleep and hence was pushing genres and subgenres of content.(https://www.fastcompany.com/40491939/netflix-ceo-reed-hastings-sleep-is-our-competition)

Youtube seems to be leveraging a similar approach of further pushing content based on channel preferneces.

Analogous to watching a particular channel on TV for a particular show,youtube's new recommendation filter will further enhance channel viewership for their content and identity.
