YouTube is to give mobile live streaming capabilities to any vlogger with more than 10,000 subscribers.
As part of an update to the app, any YouTube creator with a large enough following will be able to start a live broadcast on YouTube from their smartphone or tablet.
YouTube said the feature would eventually be extended to all users.
Video-blogging through the website has launched the careers of hundreds of online personalities, including Zoella and gaming star PewDiePie, who has more than 53 million subscribers.
'It's a launch that'll put the power of live streaming in the hands of hundreds of thousands of talented creators, giving them a more intimate and spontaneous way to share their thoughts, lives and creativity,' the video platform said in a blog post announcing the feature.
YouTube also announced a new way for YouTube creators to earn money from their live streams, an enhanced messaging service it calls Super Chat.
Followers and those watching the video can pay to highlight a message they post to the chat window during a broadcast, and keep it pinned there for up to five hours.
Those posting messages can enter the amount they would like to pay to pin their message.
'Super Chat gives viewers a chance to add a little visual flair to their chats and gives creators a new way to keep connected to their fans while earning a little money on the side,' the Google-owned firm said.
YouTube faces plenty of competition in the live streaming space.
Three of the biggest social media platforms - Facebook, Twitter and Instagram - have also recently introduced live video, giving users the chance to broadcast directly from their mobile apps.
