We have always considered that live streams are only for matches and stuff that are going on around us. But guess what this is now also used for marketing purposes and it is expected to grow more than you think. Live streaming of product launch, reviews and company productions and operations can become a great idea for your video marketing. This can include Facebook live, interviews, webinars, and explainer videos that could be shown to the world through live streaming.
I do not think this is how most people use YouTube. YouTube videos are more like blog posts, and fit more effectively into the niche of content marketing. Sure, people will comment—but they do so in a manner similar to how they comment on blog posts. They come to view and digest videos, not necessarily share their thoughts about the day. Because of this, you should approach YouTube as content marketing instead of social media marketing.
