This is long. Stop here if you're not really interested in streaming TV.
I used to pay about $350 for Charter/Spectrum, which included my internet, wifi, cable, and landline phone. I rented the modem and router from the provider, and we had four DVR boxes and two plain ole cable boxes. Got all the channels I wanted, but it went up and up, and they refused to accept my offer to pay what the new people were paying (and I offered in the kindest way I know how.)
We also pay for several of the various streaming services for things we like to watch, from $5 to $15 a month. Netflix, Paramount Plus, Peacock, Amazon Plus (comes with Prime,) ESPN+, AppleTV, and I'm told my son pays for HULU. We'd pay for those regardless of what service we use. Some would say we over subscribe, but if I want to watch something, I want to watch it, and I have the money.
Over the last month, I canceled most of the above services and transitioned to DirectTV Stream. Kept the internet and wifi because it's smoking fast, and there's no real good alternative 'round here. Haven't needed the landline phone for years, because e'erbody has cell phones and the only time it rings is during election years.
Now we're paying $130 for DirectTV Stream connections to eight televisions (can hook up to 20 devices, if the Wifi can stand it, but I don't intend to test it), and I've got three more that I can use away from the home network. I use one at my office, one on my iPad, and one on my iPhone.
We pay $80 for the WiFi, so I've cut my bill by almost half, eliminated the problems that come with hardwired boxes, and the service is spectacular.
Now comes the part that gets a little confusing. We have a mix of smart tv's, and three that aren't smart, but are at least flat screen plasma or LED. DirectTV sent me one box, which hooks to Wifi, that I used to hook up my man cave TV on the back porch.
Some of the smart tv's were able to directly download the DirectTV Stream app. All good there. The ones that couldn't required either a ROKU or Amazon Fire stick. These plug in to one of your HDMI ports, require a separate power source/cord, and give you internet access, the ability to download whatever, including the DirectTV stream app, and also offer various free streaming options. No additional charges for either, and if you just had Wifi and a Roku or Amazon stick without other services, there's lots of stuff to watch.
The Amazon sticks, if you're a Prime member, can be had for about $16 each. The Roku stick is about $30. I like the way the Amazon stick installs, and it comes with a short extender that helps if your HDMI ports are somewhat enclosed.
That's all I got. I pay for way more service than I know most of you are interested in, but I like sports and streaming series, and the wife likes all kinds of stuff. It's all about the price you're willing to pay for the service you're able to access, and what you are willing to not watch at a price . . .
