SALT LAKE CITY -- How do you say "Happy Birthday" in 140 characters or less? You Tweet, of course.
Micro-blogging website Twitter turns five years old this weekend and is celebrating with a list of "tweet" statistics in an online blog.
The first Tweet ever came March 21, 2006, from company founder Jack Dorsey. It had only two words, "inviting coworkers." At the time, there were only eight employees at Twitter. That number now is around 400.
It took Twitter three years, two months and one day to reach its one billionth Tweet. Now, Twitter gets more than a billion new Tweets each week.
The site's use is growing exponentially. The average number of Tweets sent per day in the last month was 140 million, but 177 million went out just last Friday, March 11. On Saturday, March 12, Twitter picked up 572,000 new accounts. And more of those new accounts are being used on the go - use of the site on mobile devices increased 182 percent in the last year.
Some notable people/things to follow on Twitter:
@whitehouse - the official White House Twitter account
@jack - Twitter founder Jack Dorsey
@kslcom - the official Twitter account for ksl.com
