Business people may use phone calls over video conferencing, but I am willing to bet that they schedule those calls with computers, with telephone numbers they get through a computer system, which also keeps track of their notes, documents, needs and other information.
Video calls are probably simply not a good idea, but I have been in many online many-to-many meetings. Not only is it far more flexible, but it is plain easier to see shared documents and presentations when you can see it on your own screen than on some projector partly obscured by some coworkers head.
As for Netflix, it is fundamentally different compared to TV in that it puts you in control of what you want to see and when. I realize there are cable boxes now that allow you to do the same in a limited fashion, but those wouldn't have been developed without netflix, and most of them require the internet to deliver those features.
More than Internet the combination of internet and smartphones. Someone in Africa could get the advice of a doctor in the USA just with the push of a button. People have access to the biggest encyclopedia thanks to a less than a pound item.
The fact we can easily have a calculator, GPS system, access to most information in the world, have an audio and video conference with people from all around the world thanks to some small item we carry in our pockets is now taken for granted but it was missed by most scifi writers until the 90s.
Not like they can afford that advice. Or that it would do them much without treatment. Outside of special upper class cases this just doesn't happen.

Which they mainly use to settle BS quarrels about who did what, and to serve as a replacement from actually studying something...
I was thinking about this the other day. I take streaming 4K video completely for granted, but I marvel at the system of pipes that delivers natural gas and fresh drinking water to my house.
You could still run most of the modern world without the internet, replacing it with fax and telephone (century old technology at this point). It would be painful but doable. Without refrigerators society as currently structured would collapse.
