In its first year, the entertaining user-generated content helped drive significant traffic. By the end of 2005, YouTube was already seeing millions of viewers per day.
YouTube’s engagement is driven by an algorithm that combines user data and machine learning to predict which videos users might want to watch next. The algorithm makes its selections based on factors ranging from a user’s watch history to the number of comments a related video has received.
As YouTube looks to its third decade and beyond, AI and short-form content will likely be significant viewership drivers. The company has also focused on households that have left traditional cable companies.
