MLB is a major league baseball, with 30 baseball teams, including the familiar NY (new york Yankees), LA (Los Angeles Dodgers), Blogo or a pair of socks and so on.

Now MLB authorizes New Era to manufacture baseball uniforms and baseball caps for MLB products, and New Era pays MLB a sum of money every year as the use fee for using the MLB brand. As an American company that designs and produces MLB products, New Era is a leading enterprise in the industry (just like Nike's leading position in sports or north face's outdoor field).
