What is Virtual Tourism, origination of Virtual Tourism, and countries practice Virtual Tourism?

Virtual tourism involves virtual representations of tourism destinations. It evolved out of marketing and the incorporation of virtual reality at many tourist attractions like museums and amusement parks. Germany for example is a country that has used virtual tourism as a way to continue to market Germany as a tourist destination while travel is restricted presently due to the coronavirus pandemic.

Explanation:

Virtual tourism combines the ideas of virtual reality and tourism. It is usually some form of a technological representation of an actual place or attraction that lets you experience it without having to physically travel anywhere.  It is something that has kind of evolved as tourism destinations have used more virtual-reality tools to market their attractions and as attractions like amusement parks have incorporated more virtual reality experiences into their own physical attractions. This has led to hybrid experiences and made many tourists more accepting of the idea that a virtual representation can have a lot of value in and of itself. The coronavirus has disrupted international travel and has brought many countries to use virtual reality to try to keep the interest in international travel alive for tourists. Germany for example has developed 360-degree videos that take viewers on virtual tours of many attractions across Germany.
