The video is a spot-on 1980s-style advertisement for the Starcourt Mall in the fictional town of Hawkins, Indiana. Hawkins is known as a hot bed of supernatural activity. 

The ad name-drops a lot of '80s mall icons, including The Gap, Waldenbooks and music retailer Sam Goody. Only one of those is still widely in operation.
