This document describes the evolution of Twitter's website design over 6 years from 2006 to 2011. It notes the introduction of Twitter in 2006 with a light blue theme, design updates in 2008 to be less cluttered and feature better calls to action while still using blue, a wider screen friendly redesign in 2009 with trends and less blue, more insights on what's happening in 2010 with even less blue and almost no bird logo, and a prominent slogan and simplified registration page in 2011 with almost no blue or bird logo remaining.

2. Pre-Twitter (Now we know what the domain name was
worth!)

3. 2006 Twitter (Who doesn’t remember that light blue
theme!)

4. 2008 Twitter (Less clutter, still in blue, better calls-to-
action)

5. 2009 Twitter (Wide-screen-friendlier, featuring hot
trends, less blue which makes us sad and nostalgic)

6. 2010 Twitter (More insight into what’s going on inside,
even less blue, almost no sign of a bird)

7. 2011 Twitter (Prominent slogan, the ability to register
right away (at the same page), almost no blue or bird)
