Year 1 and 2 context

I am trying to decide on what channel my program would be featrued. Although the subject is childish I think that the audience for the program would not be children. 

I think it is the kind of program that would not be on main terestrial tv as there would not be much of a demand for it, but perhaps on one of the other digital bbc channels, like bbc 3 which has a lot of less mainstream shows that are less topical, and often comparative shows like this and other "top ten" shows...

I have also considered Five, but channel 5 doesn't have many shows like this one or other 'Top Ten" type shows.
