Channel 5 to push unseen Emerald City Snapchat content during 5Star ad breaks

Channel 5 is teaming up with Snapchat for a UK TV broadcast first, using the app's QR Snapcodes on-air to give fans access to bespoke content.
The campaign will run during the commercial breaks of Emerald City, an NBC-produced Wizard of Oz-esque spinoff. Shown on Wednesday nights on Channel 5's sister channel 5Star, the series follows 20-year-old Dorothy Gale's adventures after she's removed from her home turf of Kansas via the eye of a tornado.
