INXPO just put out a press release touting an upcoming product launch on March 29 that will introduce a new version of their INXPO STUDIO webcasting platform. It is advertised as stepping away from Flash towards HTML5 as the underlying technology base.
This follows a recent announcement from AnyMeeting of AnyMeeting Webinar 4.0 - moving away from Flash and "taking advantage of the latest HTML5 and WebRTC technologies." Existing customers are supposed to be able to migrate to the new version with an online upgrade request.
I spoke to another web conferencing vendor who confidentially confirmed that they also plan to release a new HTML5 version of their product this year. The way things are going, it looks like we won't have a Flash-based webinar product left by the end of 2017!
If you aren't yet using an HTML5/WebRTC compliant web browser, it's time to upgrade. Web collaboration will soon demand it. You can check your current browser's HTML5 support level at https://html5test.com/ and you can see a categorized synopsis of WebRTC support capabilities in the latest versions of the major web browsers at http://iswebrtcreadyyet.com/
If you go to that WebRTC page, you should pay attention to the fact that the rows with the least completion deal with Multiple Streams, Simulcast, and Screen Sharing. That is extremely problematic for web conferencing vendors and means we can expect to require supplementary installable executables to handle screen sharing and other types of multi-party communication within web conferences. The underlying platform technology can't handle those aspects yet.
