title: Social Media and Scientific Meetings: Education Exhibit "Likes" at the Radiological Society of North America Annual Meeting.
abstract: OBJECTIVE
  Viewers of electronic education exhibits at the 2013 and 2014 Radiological Society of North America meetings had the opportunity to "like" exhibits, as one might "like" a Facebook or an Instagram post. The purposes of this study were (1) to evaluate for a relationship between exhibit popularity and receiving an award or RadioGraphics invitation, (2) to evaluate for a relationship between exhibit recognition and subsequent popularity, and (3) to quantify and compare the electronic education exhibit likes at the 2013 and the 2014 meetings.
  
  
  METHODS
  Exhibit likes were recorded at the midpoints and ends of both meetings. Data analyses were performed by means of one-way analysis of variance and chi-square tests.
  
  
  RESULTS
  There were similar numbers of electronic education exhibits at the 2013 (1856) and 2014 (1793) meetings with no significant difference between meeting years in the number of exhibits chosen for awards (423 vs. 404, P = 0.88) or for RadioGraphics solicitation (190 vs. 169, P = 0.46). In both meeting years, there were statistically significant associations between initial and overall exhibit popularity and exhibit recognition, as well as between exhibit recognition and subsequent popularity. A 152% increase in total likes recorded was observed at the 2014 meeting as compared to the 2013 meeting (11074 vs. 4391, P < 0.0001).
  
  
  CONCLUSIONS
  Popular exhibits were significantly more likely to receive awards and RadioGraphics invitations. Receiving an award or RadioGraphics invitation was associated with subsequent increased exhibit popularity. Significantly more likes were recorded at the 2014 Radiological Society of North America meeting than at the 2013 meeting.
