Mine are:
Youtube- I do consider them a streaming service because they do have a collection of movies and TV shows for free
Peacock- They have WWE, sports, a lot of new release movies, and one of my favorite weekend shows, On Patrol Live
Paramount Plus- They have all the classic Nickelodeon shows I grew up with
Honorable mentions go to:
HBO Max- They have a complete collection of Studio Ghibli films, Old sitcoms like Family Matters and Fresh Prince, and old Cartoon Network shows. However, one of their most significant drawbacks to me is price.
Disney Plus- I love Disney. All of the classic animated movies are there. They are the only streaming service with all of The Simpson's episodes. Like HBO Max, the biggest drawback can be the price, but for $12.99 a month, you can get Hulu and ESPN Plus, so I think that's a hell of a deal.
