I’ve been asked from a few sources about what works I’ve come across that are Quality Kids Entertainment. The following is a list of such works, however, many I have not viewed first-hand (TV shows) and so I cannot attest to their quality. Just about all, however, I’ve read reviews on or noticed they’ve won awards, or I think they’re innovative. They are also for different age groups.
‘To Love Veronica Bee’ is a book by Sarah Boland that has an accompanying website that readers can contribute too. It is not available OS but I think it is a good example of a cross-media work using print. (Aus)
