I've never understood the term "cable cutter" or "cord cutter" since the streaming device has to receive the stream from somewhere, usually the cable TV provider.
I used to have a DSL from ATT but it's not nearly fast enough for streaming.
I have Roku as well. If you like British murders mystery TV series there a lot on Britbox, which is only $5.99/month.
We’ve been getting ACORN TV since it became available. Best British and Empire TV. Easy to use interface. Good customer service. $49.99/year when bought by the year.
