"Contemporary Christian Music (CCM) has grown over a long period of time. Its foundations are evident in the early hymns of various Protestant faiths. Overtures of intimacy and sentimentality were mixed with Christian music in the 19th century as the feminine ideal of piety combined with the temperance crusade emerged. Even militaristic themes characterized hymns in the early 20th century as the world and the United States fought several major wars. By the 1960s, however, Evangelicals began to realize that "Bringing in the Sheaves" on Sundays couldn't begin to compete with weekday broadcasts of "Hey Jude" and "I Can't Get No Satisfaction," especially among younger listeners. Composer Ralph Carmichael began the CCM renaissance with pieces such as "Pass It On" and "He's Everything to Me." Musical creativity burst onto the Christian music scene as the younger generation brought its hippie culture, with music largely devoid of theological divisions, into various churches."
