A megachurch is a Christian church that has a very large congregation averaging more than 2,000 people who attend regular weekly services. As of 2009, the largest megachurch in the United States was in Houston Texas, boasting an average weekly attendance of more than 43,000 (Bogan 2009). Megachurches exist in other parts of the world, especially in South Korea, Brazil, and several African countries, but the rise of the megachurch in the United States is a fairly recent phenomenon that has developed primarily in California, Florida, Georgia, and Texas. Since 1970 the number of megachurches in this country has grown from about fifty to more than 1,000, most of which are attached to the Southern Baptist denomination (Bogan 2009). Approximately six million people are members of these churches (Bird and Thumma 2011). The architecture of these church buildings often resembles a sport or concert arena. The church may include jumbotrons (large-screen televisual technology usually used in sports arenas to show close-up shots of an event). Worship services feature contemporary music with drums and electric guitars and use state-of-the-art sound equipment. The buildings sometimes include food courts, sports and recreation facilities, and bookstores. Services such as child care and mental health counseling are often offered. Typically, a single, highly charismatic pastor leads the megachurch; at present, most are male. Some megachurches and their preachers have a huge television presence, and viewers all around the country watch and respond to their shows and fundraising. Besides size, U.S. megachurches share other traits, including conservative theology, evangelism, use of technology and social networking (Facebook, Twitter, podcasts, blogs), hugely charismatic leaders, few financial struggles, multiple sites, and predominantly white membership. They list their main focuses as youth activities, community service, and study of the Scripture (Hartford Institute for Religion Research b).
