I just came across this from the Brewer's Association (parent of the AHA), and I thought it was worth sharing.
The American brewing industry reached another milestone at the end of
June, with more than 3,000 breweries operating for all or part of the
month (3,040 to be precise). Although precise numbers from the 19th
century are difficult to confirm, this is likely the first time the
United States has crossed the 3,000 brewery barrier since the 1870s.
