Launched in 2005, and then acquired by Google in 2006 for over $1.6 billion, the video service began its life mostly as a web-based PC service, allowing anyone to upload their creations for everyone to see and watch.
When smartphones started becoming popular by the end of the 2000s, followed by the rise of smart TVs, YouTube apps followed, and its popularity exploded.
Google now says that over 1.9 billion users worldwide check out YouTube videos every month, and that over 70 percent of its video views come from mobile devices.
Google has branded many products with the YouTube name including YouTube Music, YouTube Premium and YouTube TV.
Whether you’re just an average Joe or a massive company, anyone can upload their videos on the service and there are no fees for those who want to watch them either.
Google does have certain rules over what kind of videos can be uploaded, including ones that are subject to copyrights infringements.
