So is Mary Tyler Moore staying? I might start watching that.
Check out the FREE Pluto tv https://pluto.tv
If you do not see in the tv guide listing a show then do a search.
They do not have Mary Tyler Moore but do have Dick Van Dyke show or The Bob Newhart Show but do have The Abbott and Costello Show.
They have several hundred tv shows with thousands of episode along with movies.
Also look at the FREE Tubi tv https://tubitv.com
I use a Roku Ultra box. Check https://www.roku.com/products/players
Then go to What to watch to Channel Store https://channelstore.roku.com/browse
Add channel that you want then in the Roku box software displayed on your tv you go to Settings> System> Software update.
Press the Home button and you will see the new apps.
Highlight one of the apps then on the Roku remote press the * and on the menu you choose Move channel and then the arrow keys to move the channels in the order you want.
