Here’s a nice infographic from Useful Social Media that shows the Social Commerce journey from back in February 2007 when the first virtual gift was sold on Facebook.
Some of the infographic highlights include:

Dec 2008 – Dell claimed $1 Million revenue in sales via Twitter
Jul 2009 – Facebook’s first retail transaction via 1800-Flowers
Jun 2010 – Disney launches group ticketing store on Facebook
Aug 2010 – Delta launches ticket purchases via Facebook
Jan 2011 – Living Social sells $20 Amazon vouchers for $10, selling over 1.3 million
Jul 2011 – Facebook stops Facebook Deals

This timeline shows how much growth Facebook commerce has enjoyed over the past few years and how important it’s going to be for 2012. Mark Zuckerberg commented, “If I had to guess, social commerce is the next area to really blow up.”
