Amazon acquired Wondery nearly five years ago as part of a push to expand its catalog of original audio content.

In a memo to staff obtained by Deadline, Steve Boom, Amazon’s vice president of audio, Twitch, and games, said the rise of video podcasting has created “different audience needs” and requires “distinct discovery, growth, and monetization strategies” compared to traditional audio-only narrative podcasts.

Amazon on Monday said it would lay off 110 people in its audio division Wondery, as more podcasts are including video.
