"In the past several months, many museums have begun using live video chat as a way to enhance and foster new online discussions and interactions between museum educators and the public. One of the most popular tools has been Google Hangouts which is part of the Google+ social network. It allows for up to 10 users to video chat together and gives them the ability to broadcast the video stream live to a large audience and even record the session for future viewing. The recorded video, which is archived on the museum’s G+ page and YouTube channel, can be shared on various social networks. In addition, the videos collect (limited) analytics information so museums can track the attention it receives. Users who express interest in a museum video session ahead of time can be alerted when it is about to begin via Google+ email messaging."
