In 1950, New Era was the only hat manufacturer supplying products to major sports teams, and produced products for the Brooklyn Dodgers, Cincinnati Reds, Cleveland Indians, and Detroit Tigers. In 1974, 20 of the 24 major league teams signed contracts with New Era, and the business expanded steadily. In 1978, New Era placed an advertisement in a news newspaper saying that customers could get the same caps as professional players for $12.99, which caused a great response. In the late 1980s, wearing the same caps as professional players became popular among baseball fans. In 1991, New Era was selected as the exclusive supplier of MLB on-field caps, as stipulated by several companies. The official professional cap collection, the Diamond Collection, was renamed the Authentic Collection, and the batter silhouette logo, which is still used today, was placed on the back of the cap. The name Authentic Collection was also only allowed to be used by suppliers of official equipment. In 1993, New Era obtained the exclusive right to manufacture on-field caps for all MLB teams. They then became the official supplier of the league. They then opened offices in the UK, Japan and Austria. Today, they have grown into one of the world's largest headwear and apparel brands, and are widely known in the street fashion world.
