Quick answer
IPTV grew out of early-1990s experiments sending video over the MBone, an experimental multicast network. In 1995 Precept Software released a product called IP/TV, and Cisco acquired Precept in 1998. In the UK, Kingston Communications launched one of the first IP-based TV services in Hull around 1999-2000, followed later by BT Vision, BBC iPlayer, YouView and Freely.
IPTV started as a research idea in the early 1990s, became a named product in the mid-1990s and reached UK homes as a commercial service around the turn of the millennium. There was no single launch day. Instead, internet television developed in stages, as networks became fast enough and cheap enough to carry video that people would actually want to watch.
This article traces those stages, from academic experiments to the broadband-delivered live channels many UK households use today. For an explanation of the technology itself, see how IPTV works.
| When | Milestone | Why it mattered |
|---|---|---|
| Early 1990s | Multicast experiments on the MBone | Showed that live audio and video could travel over IP networks |
| 1995 | Precept Software releases a product called IP/TV | One of the first commercial uses of the IPTV name |
| 1998 | Cisco acquires Precept | Signalled that networking companies saw video over IP as a serious business |
| Around 1999-2000 | Kingston Communications launches KIT (Kingston Interactive Television) over ADSL in Hull | One of the earliest IP-based TV services in the UK |
| 2006 | BT Vision launches | Brought broadband-connected TV to a national UK audience |
| December 2007 | BBC iPlayer launches its streaming service | Made on-demand internet TV mainstream in the UK |
| 2012 | YouView launches | Combined Freeview channels with broadband catch-up on one box |
| 2024 | Freely launches | Offers live UK channels over broadband on compatible TVs |
The story begins with the MBone, short for Multicast Backbone, an experimental network used largely by the research community in the early 1990s. Its purpose was to test multicast: a way of sending one stream of data that the network copies to many recipients, rather than sending a separate copy to each person.
Multicast matters for television because it mirrors how broadcasting works. A transmitter sends one signal and any number of aerials can pick it up. The MBone showed that something similar could be done over IP networks, with live audio and video shared with remote participants. The picture quality was modest and the audience small, but the principle had been proven.
Ordinary homes were nowhere near ready, however. Most people who were online at all used dial-up modems that could barely handle a still image quickly, let alone moving pictures.
In 1995, a company called Precept Software released a product named IP/TV. It was designed to deliver video across computer networks, and it is one of the earliest commercial uses of the name that later became the generic term for the whole technology.
In 1998, Cisco, a major maker of networking equipment, acquired Precept. The acquisition reflected a growing belief in the networking industry that video would become one of the main things IP networks carried. At the time that was a forecast, not a reality, but it pointed the way.
Hull has a notable place in British television history. Around 1999-2000, Kingston Communications launched an IP-based television service delivered over ADSL, an early form of broadband that runs over ordinary telephone lines. The service was known as KIT (Kingston Interactive Television).
KIT is widely regarded as one of the earliest IPTV services in the UK. It showed that television could be sent into homes over a broadband phone line, years before most households had broadband at all. Services of this early kind were delivered over the operator's own network rather than across the open internet, because the public internet of the time was not up to carrying TV reliably.
In the years that followed, broadband gradually replaced dial-up in UK homes and connection speeds rose. That shift made television over IP practical on a national scale. Two developments stand out.
BT Vision launched in 2006, bringing broadband-connected television from one of the UK's best-known telecoms names to a national audience. For many people, services like this were their first experience of choosing a programme to watch over broadband on their main TV rather than a computer. Today BT TV and EE TV continue to offer broadband-connected TV.
The biggest shift in public habits came when BBC iPlayer launched its streaming service in December 2007. Catch-up television in a web browser was suddenly easy: no special box, no extra subscription, just a broadband connection. iPlayer helped make the idea of watching TV over the internet feel normal to a broad UK audience, and today it offers live channels as well as on-demand programmes.
Today other UK broadcasters offer their own apps, such as ITVX, the Channel 4 app and My5, alongside subscription on-demand services such as Netflix and Amazon Prime Video. All of these are forms of internet-delivered television, even if few people call them IPTV.
As more households came to have both an aerial and a broadband connection, there was a clear appeal in combining the two. YouView launched in 2012 with that hybrid approach, bringing together Freeview channels received through the aerial with broadband-delivered catch-up on one box and one guide.
This hybrid model was significant because it treated broadcast and IP delivery as partners rather than rivals: live channels could come from the aerial while missed programmes came over broadband, all presented in one place.
The most recent milestone in this history is Freely, which launched in 2024. Freely offers live UK channels over broadband on compatible TVs, so viewers can watch live television without relying on an aerial or dish. In many ways it completes a journey that started with the MBone: live TV, delivered over IP networks, to ordinary homes.
Remember that whichever way live TV reaches you, aerial, satellite or broadband, you need a TV Licence to watch or record it in the UK, and to use BBC iPlayer.
Looking back across three decades, a few lessons stand out for anyone choosing a service now:

No single person invented IPTV. It developed from research into multicast on the MBone in the early 1990s and from commercial products that followed, such as Precept Software's IP/TV in 1995. Many engineers and organisations contributed over time.
Kingston Communications' KIT (Kingston Interactive Television), launched in Hull over ADSL broadband around 1999-2000, is generally regarded as one of the earliest IP-based TV services in the UK.
In the broad sense, yes. BBC iPlayer delivers programmes and live channels over the internet using IP, which is what IPTV means. It is usually described as an OTT or streaming service because it runs over the open internet rather than a managed operator network.
Early services ran over the operator's own network, typically with a box supplied by the operator. Today most internet TV is OTT, streamed over whatever broadband you have to apps on smart TVs, sticks, phones and computers, using adaptive streaming to cope with changing speeds.
