Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fiber-optic cables. This contrasts with broadcast television (also known as terrestrial television), in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television; or satellite television, in which the television signal is transmitted by a communications satellite orbiting the Earth and received by a satellite dish on the roof. FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables. Analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation.

All the cable-replacement services offer some type of free trial period, so you can try before you buy. Because most require a credit card number, you’ll have to keep track of when the trial period expires and cancel if you don't want to continue the service. And remember that package details can change often, so check the latest offers before signing up.
But cable providers didn't factor in that the internet they provide would become their worst enemy via access to streaming video. Services like Netflix, Hulu, and Amazon Video are the most well-known names in what's become known as "cord cutting"—doing away with pay TV and using over-the-air (like the old days) or internet-based services to get all your "television" programming. That means no more paying a huge monthly fee for thousands of hours of TV you don't watch (in theory). Instead, you pay individual services for a la carte programming. It's a lot like paying for just what you watch. Almost.
To put the scale of the potential threat of cord-cutting in perspective: for more than a year now, Netflix has had more subscribers in the United States than cable television, and the speed of changeover is only increasing. According to eMarketer, an estimated 22.2 million people switched from cable subscriptions to streaming content in 2017, a 33.2 percent growth over the previous year.
Step 3: Cancel your pay TV subscription.  Even if you are unsure that you have all your shows covered without cable, cancel anyway. Like me, you will realize a lot of the stuff we watch is simply because it’s on. You’ll also discover there is a lot higher quality TV shows are not on traditional TV. Cancel now and start saving today. If you don’t like being a cord cutter, your pay TV company will gladly take you back.
