Prior to the establishment of the RIRs (Regional Internet Registries) the IANA handled IPv4 allocations directly and without regard for geography. During that time most of the early adopters with US government, US Universities, and US Corporations. Several US Universities and Corporations (for easy examples, GE and MIT) simply asked early enough for IP addresses and got entire /8 allocations. Sure, when the RIRs were built they were assigned roughly equal shares of the remainder of IPv4 space, but it certainly failed to account for those early years of early adopter allocations, which did accidentally favor the US heavily.
