We are retired on very limited income and get Prime TV and Paramount + TV via our children setting up our tv with family sharing. We have our own sign in character icon for each channel. These 2 streamers allow sharing within family groups.
There are many free services, some a lot better than others. It is all personal preference.
Some service allow both on-demand and also streaming like cable used to do.
I like the free Youtube, Pluto TV and Roku TV. Besides new content, sometimes I just like noise in the background. I have to admit that I am a court junkie. Court TV, Matlock (both original and new), US and British mysteries and I admit to have seen every Perry Mason episode multiple, multiple times.
