San Francisco, June 30 : US-based free streaming app Plex has laid off about 20 per cent of its workforce due to a drop in overall advertising revenue, the media reported.

According to The Verge, every department has been affected due to the layoff and about 37 workers lost their jobs.  "Plex’s ad business has been 'significantly impacted' by the downturn in global advertising markets, and unfortunately, we cannot know how long ad markets and pricing will continue to be depressed and volatile," Plex CEO Keith Valory was quoted as saying.
