IPTV services may be classified into three main groups:
- live television, with or without interactivity related to the current TV show;
- time-shifted programming: catch-up TV (replays a TV show that was broadcast hours or days ago), start-over TV (replays the current TV show from its beginning);
- video on demand (VOD): browse a catalog of videos, not related to TV programming.
Definition from: http://en.wikipedia.org/wiki/IPTV
The IPTV now have to regulate online media rather than just regular TV and keep an eye on the whole of the internet, meaning they have a much more challenging task than in previous years. 10 or 20 years ago they would just have to keep an eye on just the TV channels that broadcast the shows, whereas, nowadays they have to monitor the whole of the internet which is becoming increasingly difficult due to illegal downloads and pirating.
Consumers stand to benefit the most as it is increasingly difficult to regulate and monitor what every consumer wants so therefore the consumer benefits the most.
