IPTV stands for Internet Protocol TV. Simply put, it’s a means of delivering TV programming through the Internet as opposed to cable or satellite TV broadcasts.
The Internet Protocol that is used to deliver TV content is the same as that used for data transmission over the Internet.
As such TV shows can be accessed through smart TVs, smartphones, tablets, and computers. In short, any device that supports an Internet connection is capable of supporting IPTV if a particular service allows it.
Among the comprehensive range of programming supported by IPTV are live TV, on-demand movies, and also TV shows. On top of that, video-on-demand (VOD) and time-shifted programming are available.
Time-shifted programming in IPTV allows you to watch a TV show at a different time, other than the time when it was originally broadcast.
For example, you can watch a 4 pm show at 7 pm after returning from work. You don’t have to wait for a rerun of the program.
This is made possible through pause, rewind, and fast-forward functions available on the IPTV set-top box.

IPTV is not a recent invention. It has been around since the 1990s. It has its origins in streaming video.
The earliest attempts at streaming video were undertaken with such technologies as RealVideo and QuickTime.
The groundwork was laid, but IPTV didn’t take off until the early 2000s. This was after broadband Internet became available to the masses.
IPTV then was seen as a serious contender to traditional cable and satellite television services.
Early IPTV Attempts
One of the earliest examples of IPTV was the deployment of AT&T’s Homezone service in 2002.
A limited number of channels through a set-top box with an Internet connection were provided to subscribers.
Other companies, soon jumped on the bandwagon, offering their IPTV packages. Among them were Verizon’s FiOS TV and BT’s BT Vision in the UK.
The late 2000s and early 2010s saw the emergence of streaming video platforms such as Netflix, Hulu, and Amazon Prime Video.
They were instrumental in fuelling the adoption of IPTV.
Today, IPTV is a popular alternative to traditional cable and satellite television. The number of providers has increased tremendously, each providing various packages and services.
Advantages of IPTV
