Now this sounds interesting. Gatwick Airport have started broadcasting children’s stories on the audio social network SoundCloud (a sort of audio YouTube) and are looking for children’s authors to send them stories. As far as I can see, they don’t pay, but the author retains the copyright which means you can send it elsewhere afterwards, plus you have, potentially, a huge audience for your work in the form of Gatwick Airport passengers.
They accept submissions by email only and you should specify whether your story is for the under 4s, 4-7, 7-9, 9-12 or 13+ age group. Here are the submission guidelines. You can also send them an excerpt from a novel if it makes sense as a stand-alone piece.
Thanks to Writers Online for the tipoff (like them on Facebook to get market tips and the latest writing news).

What a great tip! Thanks…
I have sent them a 4-7 story but not heard anything back as yet.
Hi Lou, did they respond? I am thinking of sending one. Thanks!
Hello Feng. I never heard back from them and unfortunately I think they were just running that particular project over the summer!
