It launched in the UK in 1989 and the Discovery Network now reaches 14 million adults monthly.
The dictionary definition of Discovery is "to be the first to find out about or to learn about for the first time".
This is what the Discovery Channel aims to do.
It tells real life stories about diverse genres from motorbikes to archaeology, science to modern myths, and from history to engineering.
Its viewers agree – the Media DNA survey tells us that it is the most inspiring, innovative and entertaining TV channel and one of the most informative media brands there is.
According to Media DNA, the Discovery Channel is the media brand that viewers feel time is most well spent with – over all other media brands on the survey – quite an accolade.
And because Discovery viewers know that they will find inspiration on the channel, it is the most specially chosen TV channel as well as the most opinion-influencing TV brand there is.
For example, one of the weirder things that Discovery viewers would know is that in 1989, a 50-million tonne asteroid travelling at 20km per second came within six hours of destroying the Earth.
These viewers would also know that one of the worst jobs in history of the last 2,000 years was being Henry VIII's "Groomer of the Stool!"
