Although overall Twitter usage has nearly doubled since the  Pew  Research  Center’s  Internet  &  American  Life   Project first asked a stand-alone Twitter question in November 2010, the 15% of online adults who use Twitter as of early 2012 is similar to the 13% of such adults who did so in May 2011.

Twitter use among 18-24 year olds increased dramatically between May 2011 and February 2012, both overall and on a “typical day” basis
Twitter use within the overall population remained steady over the last year, and usage rates within most major demographic groups changed little over the same time period. The youngest adults (those between the ages of 18 and 24) are the primary exception to this trend—nearly one third of internet users in this age group now use Twitter, up from 18% in May of 2011 and 16% in late 2010.3 Twitter use by those in their mid-20s to mid-40s largely leveled off in the last year after roughly doubling between late 2010 and mid 2011.

TWITTER HISTORY
Evan Williams on the genesis of Twitter, ICWSM, April 2007:
• A side project started on a whim; Jack
Dorsey’s idea; launched Oct, 2006.

• Wanted a ubiquitous status message. • A community of people answering the
question “what are you doing?”

• Exploded at SXSW; good for collective
backchanneling; SF earthquakes.

• “Ambient intimacy” • Huge API usage was unexpected, as was the
rise of the @ sign for replies
