But the point of the thread to get more orginal British content is vaild.
There's an overarching question whether Britain can actually produce more children's programmes that kids want to watch. Minecraft and civil aviation are not conventional genres of programmes for a children's TV channel.
Anything if presented inappropriately can become a "not conventional genre" for children's TV. Minecraft is unfortunately part of the scene now and is probably no more unconventional than Gamemaster was.
I find it cause for concern how many CBBC and CITV programmes from the late 1990s and early 2000s are now obscure and largely forgotten with few (or even no) videos on YouTube or even mentions on the internet. It makes one wonder whether many kids enjoyed such programmes or even watched them, although I think that there are some unsung heroes here and there.
I hardly think the world's going to cave in just because nobody can remember a TV show that went out in 1999. The more likely explanation is that by this point and the explosion in TV channels and their need for content both new and old means there is SO much content out there and more being made every day that nobody will see anywhere near probably half of it in their lifetime. This situation will only get worse as time and more content is created.
