If that sounds familiar, it's because Snapchat allows you to do something similar. Inside that messaging app, you can tap to share video with the person you're already having a text conversation with in a flash. Facebook's version works pretty much the same way with an Instant Video icon situated at the top of the window. As long as you and the person you're talking to are both running the latest version of Messenger for Android or iOS, you'll be able to employ the feature. Instant Video only works as long as you keep the chat open and you can continue conversing via text while the window floats over your chat. Audio is turned off for the recipient of the video by default.

This isn't the first time Facebook or one of its apps has taken cues from Snapchat. Instagram Stories arrived in early August to compile images and videos in a format that's very similar to Snapchat's own Story feature. Facebook also nabbed face-swapping app Masquerade back in March to add photo filters to its arsenal of apps. In fact, the social network has already announced that those features would be available in Facebook Live at some point. Zuckerberg & Co. have clearly taken notice of Snapchat's popularity, so it'll be interesting to see it Facebook decides to take any more inspiration from that app in the future.
