By the end of 1906, most leaders from Azusa Street had spun off to form other congregations, such as the Apostolic Faith Church, 51st Street Apostolic Faith Mission, the Spanish AFM, and the Italian Pentecostal Mission. These missions were largely composed of immigrant or ethnic groups. The Southeast United States was a particularly prolific area of growth for the movement, since Seymour's approach gave a useful explanation for a charismatic spiritual climate that had already been taking root in those areas. Other new missions were based on preachers who had charisma and energy. Nearly all of these new churches were founded among immigrants and the poor.

Many existing Wesleyan-holiness denominations adopted the Pentecostal message, such as the Church of God in Christ and the Pentecostal Holiness Church, and are now Holiness Pentecostal denominations. Holiness Pentecostals, such as the Apostolic Faith Church, affirm three works of grace: (1) New Birth, (2) entire sanctification, and (3) Baptism with the Holy Ghost. The formation of new denominations also occurred, motivated by doctrinal differences between Holiness Pentecostals and their Finished Work Pentecostal counterparts, such as the Assemblies of God formed in 1914 and the Pentecostal Church of God formed in 1919—these represent Finished Work Pentecostal denominations. An early doctrinal controversy led to a split between Trinitarian and Oneness Pentecostals, the latter founded the Pentecostal Assemblies of the World in 1916 and the United Pentecostal Church in 1945.

Today, there are more than 500 million Pentecostal and charismatic believers across the globe, and it is the fastest-growing form of Christianity today.The Azusa Street Revival is commonly regarded as the beginning of the modern-day Pentecostal Movement. Wiki.
