What is Blogger?
Computer Desktop Encyclopedia, Blogger is:
"A Web site launched in 1999 from Pyra Labs, San Francisco, CA (www.blogger.com) that provides the tools for creating blogs (Weblogs). After users select a pre-designed template or create one with their look and feel, every posting entered on Blogger is published to the Blogger page on their Web site automatically. In early 2003, Blogger was acquired by Google. "
