If you have a TV with a built in digital tuner and a simple HDTV antenna, you should be able to just turn your TV on, do a channel scan and get all the network TV stations in their full HD glory! In fact, in many cases you'll get a higher definition signal when watching over the air as they are often sent in lower definition via your cable provider.
I have Comcast for internet but included the basic TV package since our OTA antenna does not pick up all local stations well in our area. PBS does not come in at all. Playon is a great addition to our Roku which we use with Hulu Plus to catch up on the TV shows we don’t have time to watch when they are on (I’m a Castle addict). I try to keep up with new private channels and plugins periodically. I also have a Touchpad and downloaded a wonderful app for $2 called Video Flood HD to stream other shows I can’t get elsewhere, including HGTV. Not sure if something like it is available for other platforms, but it would be great if a similar app was available to integrate into Roku or Playon.
Google Fiber is really changing the ISP game. Every city they begin offering high-speed broadband in immediately sparks price competition. While they offer gigabit internet at $70 per month, you can also get a 25 Mbps internet connection for only $15 per month. This easily makes them the best internet service provider for those looking to cut the cord.
General idea: As you can tell by the name, CBS All-Access is a clutch streaming service to have if you really like CBS shows like Star Trek: Discovery, The Good Doctor, and Criminal Minds (but let's be real, most people pay for it specifically for Star Trek). This service is a little different as it's not giving you a selection of different channels, but you will have access to over 10,000 episodes of classic shows as well as news from CBSN. CBS is also the channel that covers a lot of sports (like NFL games) and award shows (like the Grammys), so an All-Access subscription is nice to have in your back pocket when important live events like those are coming up.
This year alone, some 6 million people are expected to ditch satellite and cable, causing a major pain point for the providers of digital entertainment. Welcome many of the same companies (DirecTV and Dish Network), along with YouTube, Hulu and Sony, in a different sort of offer. A smaller collection of channels, along with broadcast TV locals, no equipment required, and an average price of around $40 monthly. (Along with your internet subscription.)
