The study was done for October for Canadian businesses and RIM was numero uno for the most active company in social media. The index ranks the top companies in Canada on their use of Twitter, Facebook and YouTube. The score was out of 100 and RIM got 98.7, so an A!
There are also individual ratings for each of the social medias. For Twitter they came in 4th because their number of tweets was lower, but they do retain the highest Twitter followers. Youtube they are 2nd place for number of views. For Facebook they are number one.
If you consider the past few days alone, RIM has been pumping out the tweets, interview videos and facebook posts.
