by not only producing and distributing motion pictures, but by entering into exhibition as well. On October 6, 1927, Warner Bros. released The Jazz Singer, starring Al Jolson, and a whole new era began, with "pictures that talked," bringing the studio to the forefront of the film industry. The Jazz Singer played to standing-room-only crowds throughout the country and earned a special Academy Award for Technical Achievement. Fox, in the forefront of sound film along with Warner Bros., was also acquiring a sizable circuit of movie theaters to exhibit its product. The majors during the Golden Age Between late 1928, when RCA's David Sarnoff engineered the creation of the RKO (Radio-Keith-Orpheum) studio, and the end of 1949, when Paramount divested its theater chain—roughly the period considered Hollywood's Golden Age—there were eight Hollywood studios commonly regarded as the "majors". Of these eight, the so-called Big Five were integrated conglomerates, combining ownership of a production studio, distribution division, and substantial theater chain, and contracting with performers and filmmaking personnel: Loew's/MGM, Paramount, Fox (which became 20th Century-Fox after a 1935 merger), Warner Bros., and RKO. The remaining majors were sometimes referred to as the "Little Three" or "major minor" studios. Two—Universal and Columbia (founded in 1924)—were organized similarly to the Big Five, except for the fact that they never owned more than small theater circuits (a consistently reliable source of profits). The third of the lesser majors, United Artists (founded in 1919), owned a few theaters and had access to production facilities owned by its principals, but it functioned primarily as a backer-distributor, loaning money to independent producers and releasing their films. During the 1930s, the eight majors averaged a total of 358 feature film releases a year; in the 1940s, the four largest companies shifted more of their resources toward high-budget productions and away from B movies, bringing the yearly average down to 288 for the decade. Among the significant characteristics of the Golden Age was the stability of the Hollywood majors, their hierarchy, and their near-complete domination of the box office. At the midpoint of the Golden Age, 1939, the Big Five had market shares ranging from 22% (MGM) to 9% (RKO); each of the Little Three had around a 7% share. In sum, the eight majors controlled 95% of the market. Ten years later, the picture was largely the same: the Big Five had market shares ranging from 22% (MGM)
