For this, the date_added field was used to derive the year.

Visualizing tv shows versus movies over the years

The bar plot below shows the proportion of movies to tv shows added by netflix over the last 14 years. In 2008 there was an equal number of tv shows and movies introduced by netflix. But in the four years that followed, netflix only chose to add movies to its list of content. From 2013 onwards it decided to also start adding more tv shows, however the pattern is pretty erratic up until 2018 when there is a dip in the number of tv shows added against movies. From 2018 onwards, there is a slow but steady increase in the number of tv shows added by netflix in comparison to the number of movies.
