Evangelism

Since its inception, Christianity has seen a consistent and dramatic increase in its number of adherents.

Internet
In the 1940's, the Lausanne Movement was started in order to help Christendom evangelize globally with greater effectiveness and thousands of Christian leaders from around the globe meet regularly to increase the effectiveness of Christian evangelism.

In 2006, Alan Beeber of Campus Crusade for Christ International (CCCI) (one of the world's largest evangelism organizations) predicted that internet evangelism will result in more conversions than all other forms of evangelism for CCCI combined.

YouTube
YouTube reaches a lot of people and the YouTube search engine is the second largest search engine in the world. At YouTube, Christians and Christian creationists have faced problems with atheist/evolutionist cyberbullies, but they have developed methods to overcome this problem.
