The beginning
E4 launched on Sky Digital and Cable (NTL & Telewest) on 18 January 2001, as the new digital channel from Channel 4, dedicated to entertainment with a 2pm to 4am daily schedule.
Ali G, at its launch in a specially recorded introduction, said: "As we all know, news, documentaries and nature programmes ruin normal telly. That is why Channel 4 is invented a new station called E4, which they say is gonna have none of that crap on – and be even better than Channel Five".
The channel joined the Top Up TV line-up in March 2004 and became free-to-air in May 2005 when it launched on Freeview
E4 pioneers the spin-off show
Long before ITV's 'Xtra Factor' and the BBC's 'The Apprentice: You're Fired', E4 paved the way for the spin-off show, producing associated stand-alone shows to accompany and add value to hit terrestrial reality formats.
Programmes such as 'Shipwrecked Extra', 'Big Brother's Little Brother' and 'Big Brother's Big Mouth' pioneered a new TV format.
Here's a look back at some of its most memorable shows and idents.
