Televisions have come a long way since 1926 when Scottish inventor John Logie Baird publicly demonstrated his new invention. The first colour broadcast took place 50 years ago on 1st Janurary 1954, however the technology wasn’t cheap, and so many people didn’t have access to a colour TV until the mid to late 1960s.
4K broadcasting is still in development but that doesn’t mean you can’t enjoy the benefits of this new level of resolution; you can currently enjoy watching YouTube footage, Blu-ray discs and HD TV programming such as sporting events on these 4K sets. You’ll also be able to subscribe to Netflix’s 4K services.
The main differences between the two (4K and HD resolutions) are the different levels of definition between. 4K TVs have 4 times the amount of pixels on screen as HD TVs do. It’s the same resolution your local cinema would display movies in.
You can compare the resolutions here:
HD image resolution: 1920 x 1080
4K image resolution: 3840 X 2160

The full-sized version of the “4K TV Image Quality” illustration (which I’ve seen in a few places) slightly overstates the benefits of 4K vs HD.
As you say, 4K has 4x as many pixels as HD, but in that example, the middle image has 16x as many pixels as the one at the bottom! (It has 4x as many horizontally *and* vertically. But the 4x offered by 4K is the combination of 2x horizontal and 2x vertical.)
So it’s more illustrative of the leap from SD to 4K. (Although even then, the limited space means it’s not being entirely fair to SD, which never looks quite that bad!)
