YouTube is an amalgamation of many different communities surrounding varying topics such as gardening, cruse ship reviews, and video games. 

There are over 30,000 YouTube channels with 1 million or more subscribers and several hundred channels with more than 10 million. Two of the most popular YouTubers are MrBeast and PewDiePie who both have over 100 million subscribers. Both have generated more than 1.5 million dollars for charity. 

Some things that I know about YouTube are:
- The CEO of YouTube Susan Wojcicki has announced she is stepping down and will be replaced by Neal Mohan.
- YouTube was launched in 2005.
- Over 300,000 hours of content is uploaded to YouTube every minute.
