Late City Edition: Tuesday, July 23 at 9pm

This Tuesday on Late City Edition, we’re talking Twitter with Columbia Business School professor Olivier Toubia. Toubia recently co-authored the report “Intrinsic vs. Image-Related Utility in Social Media: Why Do People Contribute Content to Twitter?” in the journal Marketing Science.  Tune in to hear his findings on why we tweet, how often we tweet, and how Twitter may be trending towards more of a media consumption than contribution site.  [Photo via Shawn Campbell]
