The Azusa Street Revival of 1906 in Los Angeles is widely regarded as the key event that launched the twentieth-century Pentecostal and charismatic movements. In itself, however, it is just another in a series of revivals and "outpourings" that had begun in the late nineteenth century.
What is profoundly different in the case of Azusa Street is publicity. Indeed, it could be argued that this is a revival spurred largely by religious journalism — most notably the widely distributed stories of journalist Frank Bartleman. His accounts of miracles and transformed lives distributed to religious magazines throughout the country and around the world prompt pilgrims to visit and seek the same experiences. Ministers among the crowds return home with Pentecostal enthusiasm and ignited revivals in their own congregations. But Azusa Street remains the "mother" of all Pentecostal revivals, thanks to Bartleman.

This is actually a perfect illustration of American charismatic Christianity, where you can say you love Jesus (like the rapper “The Game” claims to do) and still frequent strip clubs (as “The Game” still does), or where you can flow in the gifts of the Spirit and become a made-for-TV preaching sensation, only to announce that God told you that you married the wrong woman, leading to a quick divorce and remarriage.
