2017 - Slack adds screen sharing to keep up with Google Hangouts


Slack now lets paid users to share live video of their screens during video calls. The feature will roll out on Slack’s latest Mac and Windows apps over the next few days. To use Slack screensharing, fire up a video call then hit the screenshare button. You can select your preferred screen if you’re using several, your webcam will deactivate, and Slack notifications won’t appear to avoid exposing any private info. Viewers will see all of your shared screen including your cursor so you can easily point things out. Slack’s native screensharing feature will compete with several integrations with third-party products it already offered, including Skype, BlueJeans, Appear.in, Google Hangouts, and Zoom.

2015 - Google Hangouts now allows to make videocalls to those who don't have Google account to fight Slack


Google now allows you to invite “guests” into a Hangouts meeting, even if they don’t have (or don’t want) a Google account. This will make it easier for you to do all your communications, at least on the video conference aspect, through this particular medium. The process has also been made simple and painless (or so we hope). All it would take is for you to invite the guests, and for them to accept through a few taps or so. They will be labeled as “external guests” and Google users will be able to invite them to a Hangouts through Google Calendar. They need to click the external link in the event description, then input their name, preferably not a silly nickname as this is supposed to be a professional conference. After doing those two simple steps, they will now be able to be part of the meeting and chat with you and your other colleagues for the duration of the virtual meeting.
