Advanced technologies like augmented reality, 360-degree video streaming, virtual sets and 3D graphics, and green screens or chroma key backgrounds all help create a unique experience for online viewers. Augmented reality creates an interactive environment from real-world elements, while 360-degree video streaming surrounds them with live action footage from every angle. Virtual sets offer realistic backdrops for where the hosts are speaking from, while 3D graphics allow producers to layer text or images over their broadcast in order to explain concepts more effectively—and  finally, green screens and chroma key backgrounds enable videographers to swap out different backgrounds on the fly without having to change locations or spend time setting up a new studio.
