Warner Bros. Entertainment Inc., also known as Warner Brothers, is an American entertainment company founded in 1923 by the Warner brothers: Albert, Harry, Jack and Samuel. In the early years, the brothers were acquiring movie theatres and distributing films. In 1913 they began producing their own films. It would be in the 1930s that Warner Brothers released what would later become one of its most famous properties: Looney Tunes. For nearly a century, Warner Brothers has produced some of the biggest television shows and movies of all time but arguably none of them are more popular than Looney Tunes cartoons. It’s these cartoons that are featured prominently on most Warner Brothers merchandise, such as its T-shirts, hoodies and hats.
