That chart is from a broader article we published last winter: https://vinepair.com/map-american-craft-brewing-history/ https://vinepair.com/map-american-craft-brewing-history/ More recently we put together a visualization of the 1977 data at https://vinepair.com/map-american-breweries-1977/ https://vinepair.com/map-american-breweries-1977/ There's also a marked up breakdown by brewery from a 1978 FTC report below the visualization.
