Which of the following things will be remembered more when we are all gone from this earth?
This is an underrated possibility IMO.
People are so funny! Don't you think that Borg and McEnroe were part of the "current affairs" and media coverage back in the day when it was your present time? Why wouldn't you remember it? Why would your girl remember something from 40 yrs ago if she has no interest in such a field? Pick any other sport! From 30-40 yrs ago one would only remember Tyson, Maradona, and a handful of other "global" athletes. But how many would remember Rummenigge,, Zico, Rajkaard, Ripken Jr. or Jerry Rice?This is an underrated possibility IMO.
Like so many sports tennis has given up building a mass audience and relies on screwing as much money as possible from existing fans. There could well be a point where the fan base just isn't there to sustain it.
I remember my whole class at school talking about Borg and McEnroe (this was a girls' school as well!) - I doubt my daughter could even name who won Wimbledon.
