Yes. Big difference in Streaming Paramount Plus on Roku, and having the cable version of Paramount Plus.
It really doesn't make common sense. I think Hulu or Spike TV might air it.
On cable...
the show can also be streamed on demand using platforms like Philo (free trial), fuboTV (free trial), hulu.
Philo. Fubo live tv and Hulu+live tv
The cable channel is "Paramount Network." The streaming service is "Paramount+."
They did a great fake review/commercial on Jimmy Fallon that basically involved the reviewers being totally confused about how to watch the show. It started with something like: Wait, paramount Network and Paramount+ are different? and ended up with something like: Fubo? Philo? Are those Teletubbies?
Yellowstone Season 6 is NOT on Peacock!
There is no season 6, at least so far. The new episodes are considered part 2 of season 5. Officially, S5 is the last, but there are rumors, especially how successful the show is. It may depend on contracts with actors and others.
Peacock will have them, but supposedly after about 6 months. This is the streaming deal the original production company made before Paramount had a financial involvement.
