K.J. Yossman Louis Theroux will deliver this year’s James MacTaggart memorial lecture, the flagship address at the Edinburgh TV Festival. The documentary maker, who also founded unscripted production company Mindhouse in 2019, has examined everything from Scientology to porn to neo-Nazis in his films. He has also turned his hand to social media, podcasting and streaming. Theroux will address the challenges broadcasters face in today’s “multi-platform universe,” how he has maintained longevity after a quarter of a century in the broadcasting industry and the pros and cons of the tech revolution we are all living through.
