The document discusses potential BBC channels to broadcast a documentary on. BBC 1 is the most watched channel but unlikely to air a low-budget documentary. BBC 2 airs some documentaries between 20:00-21:00 and has aired shows with personal experiences or less widely appealing topics. BBC 3 targets a younger audience and airs lower budget documentaries from 19:30-20:30 on niche topics. The document concludes BBC 2 would be the best choice as the documentary appeals to a large audience but uses a youthful cast.
