YouTube lately debunked their Hangouts on Air feature that was previously a part accessible via Google Hangouts on Air feature of Google+ social media platform.
As Google+ didn't meet the expected goals and once again became a relative failure for Google in addition to all the previous social media platform launched by Google like Google Buzz etc.
Google since has been making Google+ as a part of Google for Work platform and might be just limiting the neglected social media platform just for business.
As the Hangouts on Air feature is embedded within YouTube Live feature, we'll see how one can still do live streaming just like before but taking few different steps.
Follow the simple steps below to proceed.
