By mid-2009, most analog broadcasts ended in the United States as we settled into the digital age. Television stations switched to digital TV broadcasts, which meant that terrestrial stations, satellite providers, and cable providers traded in their analog signals for digital.
This new technology leveraged digital video compression for distribution, rendering analog television sets obsolete. It was around this time that HGTV (high-definition television) went mainstream, and pay-per-view programming found its way to living rooms.
A similar switch from analog to digital can be embodied by the transition from records to CDs. Just as this move enabled us to fit more data onto smaller disks, the compression of digital video channels meant that several channels could take up the same frequency space as a single analog channel. This efficient use of space allowed for improved quality and broader channel offerings.
Whether it takes the form of over-the-air, satellite, or cable broadcasting, digital signals have largely supplanted analog today. A handful of countries are still in the early stages of the digital television transition, but many have terminated analog signals completely. For those countries still moving to digital, simulcasting allows broadcasters to make the signal available as both analog and digital to reach viewers on devices built for either.

Video Streaming Leads to Cord-Cutting
Today, several live streaming services like Sling TV and AT&T TV Now threaten to replace traditional live broadcasting. What’s more, most cable and satellite services have supplemented their conventional broadcasting services with free streaming apps to compete (examples include Xfinity Stream or the Spectrum TV App).
Streaming requires two easy-to-come-by things: a smart device such as a phone or connected television and an internet connection. No cables or dishes are necessary, and users can watch a stream both on-the-go and in the comfort of their homes.
The live content is captured, compressed, often transcoded, and delivered across the internet to viewers globally using a content delivery network (CDN).

The Early Days of Analog TV
Television broadcasts first hit the airwaves in the late 1920s as analog signals transmitted from one terrestrial location to another. Radio waves carried video from the transmitter to viewers’ television sets, where an antenna would pick up the signal.
The same analog signal would go to all receivers as a smooth and continuous transmission. By tuning your television to a specific channel, viewers were able to receive transmissions on that frequency. For anyone young enough to have used a walkie-talkie, this technology functioned similarly.
And, much like with AM/FM radio, the farther away you got from the television tower, the worse the picture would be. Additionally, because stations would only broadcast a single signal to all viewers, everyone got the same resolution. These transmissions were also subject to snow and ghosting, which describe the static black-and-white effect followed by the blurry outlines best captured in The Ring seconds before Samara crawled out of the screen.
