Known especially for themed serialised real-life documentaries around social topics. Such as Big Brother and Dispatches. Channel 4 is the free live TV you want if you want to exercise your mind or get information about current affairs in Britain today.
From November 1982, just 2 years after I was born (Gary - Admin), Chan4 broadcast Brookside. This become one of the most beloved UK TV shows in history but sadly it was terminated in 2003 (gawd knows why).
This channel is another free privately owned live streams that has a public remit in its licence. Presumably, as it is piggy-backed on the equipment bought for public broadcasting. Its remit is to 'educate' a culturally diverse country with docs and reality TV. Indeed, the more experimental the better seems to be the motto, which is great.
More popular programs include; Big Fat Gypsy Wedding, The Grand National and, of course, Channel Four News.
