1. Being Human.
One of BBC Three's biggest hits, this supernatural drama - as much about the domestic as the fantastic - made stars many of its cast (BBC Three favourite Russell Tovey most of all) and established creator Toby Whithouse as a writer to be reckoned with.
2. Him & Her.
Okay, the Doctor Who spin-off started out unforgivably cheesy (exactly how many sex monsters can the planet be invaded by?) and ended up losing its way one it went to America - but in the middle, it developed into something genuinely inventive and entertaining, with the Children Of Earth mini-series especially executing a stunning tonal handbrake turn into bleak, heartbreaking drama. Without BBC Three it would have a lot less of a chance for it to find its feet.
4. The Mighty Boosh.
No comedy show this weird would ever get on one of the main channels. Ever.
6. The Fades.
Another bold, inventive and entertaining supernatural drama with a believable young protagonist, crafted by former Skins and This Is England writer Jack Thorne.
Oh by the way, Thorne is now reported to be writing the long awaited Sandman movie for Joseph Gordon-Levitt - one of the most sought-after writing gigs in Hollywood. If you want an example of how BBC Three helped nurture great talent, look no further.
7. In The Flesh.
8. Gavin & Stacey.
This is a sitcom that would just seem out of place if it debuted on BBC One or BBC Two. Telling the story of a daughter who married a complete odd-ball whilst on her gap year, the sitcom developed into one of the biggest hits of the channel in 2013.
The proposed closure is also weird because it was recently announced that Twilight's Taylor Lautner will be joining the cast at the start of the next screens. It feels weird that a returning sitcom could possibly not make it on to a TV screen.
10. Russell Howard's Good News.
11. Little Britain.
12. Glastonbury, T In The Park, Radio 1's Big Weekend.
13. BBC Three's Olympic 2012.
Remember BBC Three's Olympic coverage during London 2012? It was class. Whilst BBC One dedicated themselves to the big medals and big Olympic moments, here were hand-selected sports that you would never have watched otherwise. Like the Greco-Roman wrestling. And the swimming. And the horse dancing. THE HORSE DANCING.
Yes, in the future we will probably watch online channels with uninterrupted Olympic sport, as the BBC trialled in 2012 - but when you watch one of the 24 channels you just feel like you're the only one doing so. It's a hell of a lot less exciting.
