It is easily the least impactful of the existing majors. It was a major because the PGA used to be the association of the Tour players. The championship tournament of the Tour players warrants major status. The PGA Championship hasn't been that since the Tour broke off from the PGA over 50 years ago. The Players Championship is now the premier tournament of the Tour players. So other than media lethargy, why is the PGA Championship still considered a major?
