蘑菇短视频

Max Pearson presents a compilation of this week's Witness History programmes from the 蘑菇短视频 World Service.

Sir Trevor McDonald reflects on the 蘑菇短视频's first black producer, Una Marson, and her legacy in the development of the 蘑菇短视频 Caribbean Service.

Also, how the 蘑菇短视频 managed to broadcast through the Iron Curtain, Colombia's false positives scandal and the incredible rescue of 33 miners trapped in Chile.
