According to a poll of more than 100 association executives conducted by the organizers of IMEX and the International Conference & Congress Association, 31 percent of respondents said attendance at 2010 association meetings was higher than in previous years, while 46 percent saw no change and 14 percent reported a "slight" reduction in numbers. In the same survey, which was conducted in May, 20 percent of those polled reported higher income from sponsors and exhibitions, 40 percent reported no change and the other 40 percent said income had decreased. When asked about their projections for 2011, nearly one-third of respondents said they would be holding more meetings in 2011 than in 2010, while 53 percent expect higher attendance figures. A second IMEX survey -- this one on the social media habits of hosted buyers who attended the 2010 show in Frankfurt in May -- revealed 64 percent of 1,000 buyers used LinkedIn, 60 percent connected with Facebook, 27 percent tweeted and 23 percent used YouTube, while just 17 percent regularly followed industry blogs. Nearly half of the respondents (46 percent) said they had increased their use of social media for networking in the past six months. Among other findings, BlackBerry was the smartphone of choice, according to 57 percent of those polled.
