SAN FRANCISCO (AP) " Knock, knock, Google's video chatting app has arrived. The app, dubbed Duo, represents Google's response to other popular video calling options, including Apple's FaceTime, Microsoft's Skype and Facebook's Messenger app. Google calls this feature, "Knock, knock." Many other services require both participants to have account logins to use their video calling options. Google has been offering video calling through its Hangout feature for several years, but the internet company is now tailoring that service for business meetings.
