The first time I experienced US cable TV, back in the ancient times before Netflix and 7mate, I remember being disappointed that, even with a gazillion channels, there was still nothing I wanted to watch. Not the case now! I sat through a mind-spinning session at AIDC called What’s the Buzz, where Alison Leigh from the World Congress of Science and Factual Producers sprinted through clips of trend-setting projects from around the world. It was a lifetime’s worth of brilliant shows and daunting in showing the calibre of documentaries competing for slots.
