Rin Tin Tin, a German Shepard dog, is credited for turning the fledgling studio in a success and was so popular that he stared in 26 films. As the studio prospered, it gained backing from Wall Street, and in 1924 Goldman Sachs arranged a major loan. With this money the brothers were able to plunge into radio, a nation-wide distribution system, and were even able to build theaters.
In October of 1927, Warner Bros. revolutionized the movie business with the success of the fist "talkie" The Jazz Singer. The early 1930's at Warner Bros. was the era of the gangster dramas, musical extravaganzas, as well as the birth of Bugs Bunny, Daffy Duck, Yosemite Sam, and Sylvester and Tweety.
Warner Bros. continued to prosper and today they are one the largest producers of film and television entertainment that includes several subsidiary companies such as: WB Television, Warner Home Movies, Turner Entertainment and Hanna-Barbera Cartoons, inc. to name a few.
