Another trend is the exploration of the intersection between entertainment and technology. Documentaries like "The Inventor: Out for Blood in Silicon Valley" (2019) and "The Fyre Fraud" (2019) examine the impact of technology on the entertainment industry, from the rise of streaming services to the use of social media to create and promote content.

Music documentaries have always been a staple of the entertainment industry, but in recent years, we've seen a surge in films and series that explore the lives and careers of musicians. One of the most notable examples is "The Punk Singer" (2013), which follows the career of Kathleen Hanna, the lead singer of Bikini Kill and The Julie Ruin.

The rise of streaming services like Netflix, Hulu, and Amazon Prime has had a profound impact on the entertainment industry. Documentaries like "The Keepers" (2017) and "Abducted in Plain Sight" (2017) have used these platforms to reach a wider audience and explore complex and often disturbing themes.

So, what trends and themes are emerging in entertainment industry documentaries? One of the most notable is the focus on the creative process. Films like "20,000 Days on Earth" and "The Beatles: Eight Days a Week" offer a glimpse into the minds and workspaces of some of the most innovative and influential artists of our time.
