netflix has a plan with ads! https://help.netflix.com/en/node/126831

amazon uses prime video as a hook to get you to sign up for prime membership (which itself has been steadily increasing in price).

i’d be shocked if HBO didn’t introduce an ad-supported price tier at some point in the future. that totally seems like zaslav’s MO.

Peacock, Paramount+, Hulu, and YouTube TV all have ads or ad plans. Some even just have ads on popular shows no matter the price you pay.
