https://en.wikipedia.org/wiki/.edu#Grandfathered_uses https://en.wikipedia.org/wiki/.edu#Grandfathered_uses Domains that were already registered in edu as of October 29, 2001, were grandfathered into the system. Holders of such domain names can retain their edu domain names without regard to the current eligibility criteria. Brookings.edu was first registered 07-Sep-1996, so it would appear they are grandfathered in. Similar case for the S.F. museum, the exploratorium.edu https://domain.glass/Brookings.edu https://domain.glass/Brookings.edu
