When we went through the ordering process for Spectrum and got all the way to the check-out, we realized we never got to choose which DVR we wanted. Spectrum offers both Motorola and Cisco DVRs (neither of which stand out from competitor DVRs like the Genie or Hopper 3), and as far as we can tell, you get whichever one Spectrum decides to send you.
General idea: CuriosityStream, or as Mashable called it, "the Netflix of non-fiction," is a unique streaming service that wants to help viewers explore their universe through non-fiction documentaries. Hashtag edu-tainment. (And yes, you read that right. Three bucks a month.) Instead of offering a mix of different channels like traditional streaming services, CuriosityStream offers over 1,500 science, history, and technology documentaries that wouldn't be found on many popular channels. Topics include famous assassinations, nature, evolution, and a whole lot of space stuff. It's like your own personal museum, but you don't have to blow all your money for a ticket and don't have to deal with someone's kid running around. Unless it's your kid, that is.
Here's the deal: your local ABC, CBS, Fox, and/or NBC affiliates are broadcasting from those big towers you see on their properties. They've been doing so since before cable existed, and they're still going strong. You can get that coverage for free just by picking out an antenna that's appropriate to your location, connecting that antenna to your TV, and scanning for channels. And you'll find that it's not just the “big four” major networks: PBS, Univision, and a bunch of other channels are broadcast over the air, too. Your selection will vary depending on where in the country you are, but you should have lots of options in most urban and suburban areas, as well as in plenty of rural ones.
