If you can’t get to the exhibition but still would like to see it (and another income stream for the museum.)
A virtual guided tour of the museum, where you progress from room to room, zoom in on the exhibited pieces and get an audio presentation if you want one.
To attract the masses and sell to the best buyers.
Offer free city tours for the masses and in parallel (and during the tour) sell paid private more exclusive (both in content, the number of participants and price) tours.
Before going to an interesting place as a tourist, get to know it.
A website or app where you can download and listen, read and view a guided pre-tour to prepare you better to enjoy the actual visit to the place.
