This is the 'daddy' of TV awards ceremonies, where all the winners are picked by the viewers.
The top TV shows and presenters battle it out to be named 'most popular' in one of 10 different categories.
In 2008 the awards went a bit of a re-think, and some of the categories were changed.
The awards for actor and actress were combined, replaced by one for outstanding drama performance.
Big winners in the past have included Ant and Dec, Doctor Who and the X Factor.
One of the most memorable National TV Awards was in 2000, when presenter Judy Finnigan flashed her underwear when her dress came undone! Sorry Judy but we couldn't help but giggle...
