How did guacamole consumption become a Super Bowl thing?
A lot of it is a simple matter of supply and demand for the humble avocado.
Sara Davis, writing for Table Matters, notes the watershed seemed to occur in the 1980s, when California saw a spike in avocado farm start-ups. "This bounty, combined with the establishment of commissions to promote avocados and protect grower interests, triggered the classic feedback loop that mainstreams 'exotic' food into American culture: the more visible and widely distributed a food becomes, the less strange it seems; the less strange it seems, the more widespread it becomes."
