Zippervertising
Original book (April 2020) · p. 39

The underutilized art of advertising on custom branded fanny packs.
The term was coined by the Shanghai Szip Zipper Co., Ltd. As of February 2020, its webpage in Korean represented the only Google result for this term.
Zippervertising could be the next blockchain. A warning for all future zippervertising investors: as with all things that zip, it is a market full of ups and downs.
Except for the zippers on items like fanny packs that operate horizontally. That market has already gone sideways.
