YouTube is one of the go-to social media platforms that brands and businesses use to market their products and services online. "Why?", you might ask. Two of the most obvious reasons are its popularity and staying power. Even though the platform started way back in 2005, it's still among the top social-streaming platforms that people on the internet use daily. In fact, its user population has not dipped since its launch and is only expected to continue growing in the coming years. The video sharing and creation site currently boasts a total of 2.1 billion monthly active users.
