EXCLUSIVE: National Geographic’s climate-change documentary Before The Flood, produced by and starring Leonardo DiCaprio, has reached more than 30 million viewers worldwide who watched at least a portion of the program across linear, digital, streaming and social platforms. That is the largest sampling for a documentary in the world since 2000, and the largest ever for a National Geographic Film, according to the company. Before The Flood also has had the highest average of minutes viewed for a NatGeo film. The docu benefited from being the most broadly distributed program the network has ever released.
