Let's focus on movies only.You are right but vaccines take YEARS to develop so this one is going to be risky - and what's the payoff? Maybe 50% effective? I've read 20% for the elderly. EVERYONE is not going to get it and it's going to take a couple of years to vaccinate a significant number of people -- and even then will life return to normal? Will there be theaters and concerts? A lot of things may just disappear.
The days of the drive in are long dead, but believe it or not, there has been a micro resurgence over the past decade or so. Setting this seem,ent aside because it is so micro, let's move on to the main stream.
The movie cinema. They have gotten smaller and more expensive. Elbow to elbow with the next patron is going to be a huge problem when and if they re open. People are hyper focused on contact with another person going forward this is going to be a huge problem for movie theaters, sporting events, concerts, theater, cruise industry, travel etc ... Wherever people gather, it is going to be a consideration.
With Netflix, Amazon and all the other streaming services out there, I have to imagine that these changing times are going to play to their side of the industry. More and more people are going to opt to stay home for their movie viewing. And it's quite possible they may do it with invited friends who they know and trust. (Smaller groups.)
Online shopping is and has been and will continue to kill bricks and mortar retail. So shall the effect be for Netflix et al on the likes of Hoyts Cinemas etc...
