After the telephone was invented, it took 70 years for the number of North American households with telephones to go from 1 percent to 75 percent, but after the Internet was launched, the number of households with Internet access went from 1 to 75 percent within only seven years, according to David G. Myers in the book Exploring Social Psychology (McGraw-Hill, 2004).

Moreover, according to Internet World Stats, 694 million people worldwide were using the Internet in May 2006, but as of June 30, 2009 that number had grown to roughly 1,668,870,408, which means the number of users on this planet more than doubled in three years. What's more, the number of Internet users continues to grow on a daily basis.
