That's what I switched to, no cable. You can buy a box

I thought I would be watching more stations but I don't. I watch youtube and skip the recording and the commercials are usually 5 seconds before I click SKIP. To me youtube is like google. For example, I need to work on my short game. So I found to series on youtube that is pointing me in the right direction. No matter what I want to learn about is there.
It might be different if Streaming worked with Roku. They say they are working on that. When I have guests that want to watch regular TV shows they can watch the Streaming on their laptops or Ipad type devices. Since this only costs around $40 for Streaming and Internet it seemed like the best choice for me. But I don't need too much to be happy. I use my son's Netflix account and I have a moviepass [50 cents a day] for great sound, big screens and a pretty comfortable seat. If moviepass isn't working after I just drove to the other end of town I'll find a putting green or something else to do for free.
