Netflix! What started in 1997 as a DVD rental service has since exploded into one of the largest entertainment and media companies.
Given the large number of movies and series available on the platform, it is a perfect opportunity to flex your data manipulation skills and dive into the entertainment industry. Our friend has also been brushing up on their Python skills and has taken a first crack at a CSV file containing Netflix data. They have been performing some analyses, and they believe that the average duration of movies has been declining. Using your friends initial research, you'll delve into the Netflix data to if you can explain some of the factors that may be contributing to the shortening movie lengths.
You have been supplied with the dataset netflix_data.csv , along with the following table detailing the column names and descriptions:
