Warner Bros. Entertainment Inc. (formerly Warner Brothers Pictures, Inc.) is an American entertainment company that is a division of Time Warner and is headquartered in Burbank, California. It is one of the "Big Six" major American film studios.

The company's name originated from the four founding Warner brothers: Harry, Albert, Sam, and Jack Warner. They emigrated as young children with their parents to Canada from Krasnosielc, Poland.

Warner Bros. released 'The Jazz Singer' starring Al Jolson. This movie, which has very little sound dialogue, but includes sound segments of Jolson singing, was a sensation. It signaled the beginning of the era of "talking pictures" and the twilight of the silent era. However, Sam died the night before the opening, preventing the brothers from attending the premiere. Jack became sole head of production. Sam's death also had a great effect on Jack's emotional state, as Sam was arguably Jack's inspiration and favorite brother.

Thanks to the success of 'The Jazz Singer', the studio was cash-rich. Jolson's next film for the company, 'The Singing Fool' was also a success. With the success of these first talkies ('The Jazz Singer', 'Lights of New York', 'The Singing Fool' and 'The Terror'), Warner Bros. became a top studio and the brothers were now able to move out from the Poverty Row section of Hollywood, and acquire a much larger studio lot in Burbank.
