This led to a decrease of almost 100 million viewers between 2014-2017 according to Statista, leading Bernie Ecclestone to sell Formula 1 to Liberty Media, headed by Chase Carey in 2018. Mercedes has held an iron grip on both the drivers' and constructors' championships Liberty Media have done an admittedly stellar job in modernising Formula 1, creating a huge presence on social media and adding the highlights of every weekend session onto their YouTube channel. Furthermore, Netflix commissioned a documentary, 'Drive to Survive' to follow narratives in the sport. It became a huge success. Audiences have regrown since 2017, but are still yet to hit the same numbers as the pre-hybrid era. Liberty Media announced huge technical regulation changes in order to stifle Mercedes dominance and also cheapen research and development costs.
