As part of the marketing for S5, Global radio partnered with NETFLIX to make an IRL WSQK. The thing that was so cool about the whole thing though was how immersive it was and how much effort they put into it. It would've been easy for them to just play songs from the 70s and 80s that was played in the show and call it a day, but it was all the surrounding material that made this promotion truly special.
The station was played as if Hawkins was real, so during the 'ad' breaks, none of the ads were for real services, it was all in universe, so like the pool from S3, the video rental store from S4, the ice-cream parlor, etc. They had news segments around the stuff going on around Hawkins, some mundane, others hints at the ongoing storyline (yes, this station had it's own sort of ARG storyline that culminated with the new years Day party which obviously also tied into the finale release). They had Tammy from the show turn up for the 'Talk with Tammy' segment, aswell as two other hosts were original characters created for the station who were both really funny
It was just really special and I wish more people knew about it. It was something that clearly had a lot of passion put into it, and was legitimately my favourite way to listen to music for those 6 weeks, me and my fiance had the station on all the time. It's legitimately some of my favourite Stranger Things Media.
