Timeline of Twitter
This is a timeline of microblogging service Twitter.
|Time period||Key developments at Twitter|
|March 2006 – March 2007||Twitter launches as a product of parent company Odeo. It grows slowly until March 2007, where usage grows dramatically after it is showcased at the South by Southwest Interactive (SXSW) conference.|
|April 2007 – October 2008||Twitter grows rapidly under CEO Jack Dorsey, completing two funding rounds and launching official support for hashtags.|
|October 2008 – October 2010||Jack Dorsey steps down, and Evan Williams takes over as CEO. Twitter raises money, gets celebrity endorsements and publicity, and continues to grow rapidly. The first tweet from space occurs during this period. Twitter also announces that it will start allowing for advertising in the form of promoted tweets – "ordinary tweets that businesses and individuals want to highlight to a wider group of users."|
|October 2010 – October 2013||Evan Williams steps down as CEO, and Dick Costolo takes over. The company starts making acquisitions, closes a $800 million Series G, puts its advertising plans to fruitions, launches site redesigns, and continues to grow.|

Rather, it seeks to more intelligently help people with the on-boarding process as well as helps seasoned users navigate through what might otherwise be a very messy feed.|
