During this era, the most popular recordings and musical radio shows included Western music. Western swing also developed during this time. Decline in popularity/1950s-70s The Western Writers of America was formed in 1953 to promote excellence in Western-style writing, including songwriting. Late 1950s, Frankie Laine recorded TV drama Theme "Rawhide". In 1964, the Country & Western Music Academy was formed in an effort to promote Western music, primarily in the Western United States. The Academy was formed in response to the Nashville-oriented Country Music Association that had formed in 1958. The Academy's first awards were largely dominated by Bakersfield-based artists such as Buck Owens. Over time, the Academy evolved into the Academy of Country Music and its mission is no longer distinguished from other country music organizations. By the 1960s, the popularity of Western music was in decline. Relegated to the country and western genre by marketing agencies, popular Western recording artists sold fewer albums and attracted smaller audiences. Rock and roll dominated music sales and Hollywood recording studios dropped most of their Western artists (a few artists did successfully cross between the two, most prominently Johnny Cash, whose breakthrough hit "Folsom Prison Blues"(1955, Live=1968) combined a western theme with a rock-and-roll arrangement). In addition, the Nashville sound, based more on pop ballads than on folk music, came to dominate the country and western commercial sales; except for the label, much of the music was indistinguishable from rock and roll or popular classes of music. The resulting backlash from Western music purists led to the development of country music styles much more influenced by Western music, including the Bakersfield sound and outlaw country. Willie Nelson, Waylon Jennings and Kris Kristofferson were singers in outlaw country genre. In 1979 Johnny Cash recorded "Ghost Riders in the Sky (A Cowboy Legend)". Cowboy pop Authors such as Barry Mazor, Richard Carlin and John T. Davis have used the term cowboy pop to describe the music of cowboy singers in western films. Jimmy Wakely, for example, was described by Mazor as a cowboy pop singer, and he has written that "when singing cowboy movies ruled, Hollywood hardly made a distinction between the sounds of cowboy pop balladeers and another sound entirely, born in Texas, in which Jimmie Rodgers had a formative role." Several writers have emphasized that historically country music and cowboy music were not considered the same genre; for example, in her essay
