Is it possible to patent a business idea?

Question

Business Informatics

Good day.
The question arose, is it possible to patent an idea for a business?
Because this is not material, but rather a service, I didn’t find much information on this ..
Let’s say there are services like hotels.com, booking.com, airbnb.com (this is not advertising, just examples). So. Could the authors of these services get a patent for their idea? well, or is it not a patent, but simply a restriction on the creation of the same service by others?
UPD:
I'll reformulate a bit. Regarding the idea, I understand that it cannot be patented
. Let's say then whether it is possible to patent the "service".
Using the example of airbnb so that no one else can create the same service that provides the same services

Answer 3

Understand, the idea is an empty phrase. They are not patented.

Answer 4

Seriously? A patent for an idea? An idea costs absolutely nothing, every person has a couple of ideas "for a million". Without implementation, an idea is just a thought that does not change anything in the world.
