Happy Anniversary, Twitter! Here's How Twitter's Look Has Changed, From 2006 To Right Now — PHOTOS

If you were sending out a tweet on July 15, 2006, congratulations! You've been with Twitter from the start, and are officially more tech-savvy than the rest of us. That's right — July 15 marks the 8th anniversary of Twitter's initial rollout to public users. Of course, back in 2006 it was called "Twttr" and it looked — and functioned — a bit different than the Twitter we know and love and use today.

Let's take a trip down memory lane and see what TechCrunch had to say about Twttr on July 15, 2006:

Odeo released a new service today called Twttr, which is a sort of “group send” SMS application. Each person controls their own network of friends. When any of them send a text message to “40404,” all of his or her friends see the message via sms. This launched officially today, and a few select insiders were playing with the service at the Valleyschwag party in San Francisco last night.

People are using it to send messages like “Cleaning my apartment” and “Hungry”. You can also add friends via text message, nudge friends, etc. ... Users can also post and view messages on the Twttr website, turn off text messages from certain people, turn off messages altogether, etc.

TechCrunch went on to write that while every Twttr user has a public page, people probably wouldn't "want to have all of their Twttr messages published on a public website." Oops, looks like that didn't go as planned.
