Brief History Of TV in the UK and Abroad

Television has been running publicly since the first television broadcast in 1936 which was broadcast for the Alexandra Palace using Baird's 240-line broadcasting system. The year after, the BBC made the first outside broadcast with King George VI coronation but the ceremony was not broadcast as it was thought to be too sacred. Almost a decade after, the BBC creates the first television programme for children. In 1948, the first Olympic games after World War Two are also the first Olympic Games to be televised. That same year, the first regular television news programme, Newsreel, is broadcast. In 1950, the BBC had the first broadcast from in the air. This was above Saint Paul's Cathedral and they had mnay technical problems such as the vibrations from the plane causing problems for the camera. Later that decade, Queen Elizabeth I's coronation is the first coronation moment to be televised and over 20 million people watched.
The BBC were the first major broadcaster of public television for 19 years until ITV was introduced. ITV stands for Independant Television.

Every Country uses a different broadcasting colour standard. They all use either PAL, SECAM or NTSC or some variant like PAL-N. In the UK we use PAL as does most of Europe and Africa, Australia and some of Asia and South America. France, Russia and some of Africa uses SECAM whereas North America and some of South America uses NTSC.

PAL or Phase Alternating Line is a 625 line of resolution system at 25 frames per second.
SECAM or Sequential Colour with Memory is also a 625 line system and was the first colour broadcasting standard in Europe.
NTSC or National Television Standards Committee is 525 line system instead of 625 and is 30 frames per second instead of 25. This system has lower resolution compared to PAL and SECAM but a faster frame rate.

But television stopped being limited to a box when internet televsion arrived. This started in 1994 when US broadcaster ABC's world news programme was broadcast. Many television broadcaster offer their television servies online with various on demand and catch up services such as BBC's BBC IPlayer or Channel 4's 4OD. This means people can watch their regular shows whenever they want.

This means people don't have to schedule their life around a television and can watch what they want, when they want instead of the scheduled programming of television.
In 2005 Youtube was launched. A video sharing site whos poularity boomed. It allows users to upload videos and share them with the world. This makes it easier for people to produce their own shows and share them with the world.

HD or High Definition television is television with substantially higher resolution that standard definition television. The majority of television available today are High Definition. A lot of broadcasters have made HD versions of their regular SD channels such as BBC HD.

3D technology is the latest technology to be brought to televisions. Broadcasters are already making 3D versions of their channels.
