Origin of the word "blog" came into existance in 1998. It became a short version of the word "weblog" yet in 1969 the name Joe Bloggs was British slang for "any hypothetical person."
The US equivalent of this was Joe Blow which meant servant boy, perversion of bloke or when used as a verb meant "to defeat"
Blogger was launched in 199 and now gives anyone (ANYONE!) with access to the internet a chance to blog and contribute to the blogsphere.
