NBCUniversal’s E! News is doubling down on original content for Snapchat Discover. With viewership for its weekly Snapchat series “The Rundown” up by 82 percent since the show’s September premiere, E! News plans to double the output to two episodes per week. It will also do more one-off red carpet specials on Snapchat tied to entertainment awards shows — its red carpet special for the Golden Globes received 1 million views.
