The Covid-19 crisis has upended the whole professional tour (yes, it has done much more than that but this is a tennis forum so I’m focusing on the impact on tennis). It may take 12-18 months before we have widely available vaccines and it may take even longer before mass gatherings are allowed again and/or people are comfortable in them. It could be 3-4 years before we go back to what used to be normal, assuming we ever do.
Assuming society doesn’t simply collapse pro sports will need to adjust to the new reality. Most people who watch tennis do so from a screen, not in person. Most of the earnings of the sport are from TV rights, not ticket holders.
Other than the very top players, who are rich and have ample resources (monetary, human, logistic), most tennis players can’t simply not play for months, possibly years on end. It would kill off the sport. So some alternative may need to be found. We now face a new world where human-to-human contacts may have to change and tennis with it.
Given that how long before tennis chooses to hold fan-less tournaments (or much smaller fan participation where only fans who can prove they are Covid19 free can buy tickets)? Maybe accelerate the move to virtual reality as the most common way to watch tennis? Sure, we all would love to go back to thousands cheering in a large stadium but how likely is that in the next few years?
Obviously this goes beyond just tennis.
