Obviously none of you have watched Discovery much within the last few years then. The quality of programming has deteriorated massively on Discovery, and in terms of documentary channel's, its playing catch up at present with the likes of The History
Channel and National Geographic etc..
Also, there is a lot more competition within the documentary sector nowadays, especially with the BBC starting up a range of UKTV documentary channels as well as BBC Four, and Discovery is pretty shite in comparison.
If you want to watch the same types of programs constantly like they have special weeks on sharks every fookin month, then Discovery is the place to be, but it all got very repetitive many years ago.
On top of this, they havent helped themselves by diversifying their content, placing it across multiple different channels instead of the one main channel. And "Channel Of The Year" doesnt constitute an entire family of channels imho.
The quality of the actual programming on the Discovery Channel nowadays is also very cheap and tacky, and most it just rerun's of stuff they have shown a thousand times, or crap they have bought over from the US channel.
Its so bad now, you can instantly tell when its a Discovery only production, and when is a collabporation with another media organisation like the BBC, the quality is just so much better and the programs are actually watchable.
