It was found that actors and models have the highest brand earnings overall.

"Considering the huge screen presence and fanbase of popular actors, it is no surprise to see figures like Chris Hemsworth and Katherine Langford in the top five," Impressive CEO and Founder, Robert Tadros, said. "Both have also starred in successful projects on Netflix, which may have helped them to gain an even bigger following by promoting themselves on multiple platforms. There is a notable difference between the potential earnings at the bottom and top of the rankings, with actors and models garnering the highest brand earnings overall.

"Regardless, it is great to see such a variety of professions in the mix and how influential these individuals have become online from their careers."
