If it seemed like more people were keying in on Roger Federer vs. Novak Djokovic than you have observed for a Wimbledon final in quite some time, that’s because it’s precisely the case. Austin Karp of Sports Business Journal notes:
There are a number of factors in this. It’s two huge names, though it should be noted that Federer and Djokovic also played each other during the 2014 and 2015 Wimbledon championship. This was a five-set match that went deep into the fifth with a tiebreak at 12-12, and it was the first five-set finals since the two’s match in 2014.
Because these ratings are calculated by average viewership, it would not be too crazy a guess to believe that as the fifth set grew more and more dramatic, various text messages and social alerts led more eyeballs to catch the conclusion on television.
