First, there should be a position for recognizing the subject, almost unintentional factors which have an effect on history like personal passion or personal preference, chance elements which may give the push that fixes a historical drama in motion. Second, the best-known Warner sound vehicle, The Jazz Singer in the year 1927, symbolizes a key moment in the history of the US entertainment industry and accounts for the tensions in US popular culture at an intermediary moment. And third is the method the personal role Sam made to the emergence of synch sound was noticeably appreciated. (Sam Warner - Now you has jazz).

             Sam was a visionary. He cast himself, in the words of a modern Warner Bros. technician as hook, line and sinker into sound cinema, taking accountability for making all the studio's early programs, ending in his determined control of the making of The Jazz Singer. But Harry had to set up a firm financial base for extension before Sam could inflect the Warner Bros. story. The US economy was flourishing with high buoyancy in the mid of the 1920s, as the boom had been collecting energy since the Depression period of the 1890s. The film industry emerged with these conditions, was called Hollywood and had on the whole merged into an oligopoly of five major studios with straight integrated control of production, distribution and exhibition, whose products also conquered overseas markets. These studios had no intention of shaking up their flourishing industry by tricking around with new technologies and were against the idea of talking pictures. So it was the hungry strangers, the Warner brothers who were ready to take risk in the idea of breaching into the closed circle of the majors. (Sam Warner - Now you has jazz).

             When Warner Brothers, who greatly wanted entrance to the strongly conserved world of the four majors: Paramount, Fox Film Corporation, Metro-Goldwyn-Mayer, RKO presented The Jazz Singer; they were an instant success story.
