I think the Korean Wave is foreigners enjoy our pop culture which is spread abroad. I would say we have to
keep the Korean Wave developed because it can make them recognize Korea easily.
There are two methods to promote the Korean Wave.
One is developing the tourism products related to it such as K-pop and Korean movies.
For example, many foreigners are getting to enjoy K-Pop and Korean movies. If they have seen them once, they will get curiosity of Korea and interest in travelling to Korea. When it comes to this situation, we can make package tours to have them visit where the movies were filmed with beautiful and cool sceneries. Plus, they can get a opportunity to go to concerts or fan meetings for them.
The other is to promote our pop culture abroad with many events such as oversee concert and making applications or promotion videos. K-Pop is usually known to Southeast Asia. One of Korea singing groups kept the first place in a music chart there for a long time. If they hold a concert in other countries, they will be happy with they visit. Reputation and attachment of Korea will increase. Making apps for advertising Korea or promotion videos for something attractive of Korea is also good ideas. One of Korean TV shows put a video promoting for Bibimbap into Times Square in New York, which was successful.
All in all, these ways to promote the Korean Wave can lead to making good images and growth of economic in Korea. Therefore, we should go on with developing it.
