Our organization switched from Cisco's WebEx to AdobeConnect 3 years ago, en masse. It was a directive from the top executives, primarily due to a 'conflict of interest' in having a business relationship with our direct competitor. So, while the directive was initially 'groaned' at (en masse), changes in employee enthusiasm became readily apparent after a few months of use (and training). There are several key departments within our org that use AC on a daily-basis: mostly used for the typical business conference-calls/meeting room, but also used by my department for technical training purposes.
