The entertainment companies help to expand K-pop to other parts of the world through a number of different methods. Singers need to use English since the companies want to occupy markets in the other parts of Asia, which enables them to open the Western market in the end. Most of the K-pop singers learn English because it is a common language in the world of music, but some singers also learn other foreign languages such as Japanese to approach the Japanese market. Similarly, increasing numbers of K-pop bands use English names rather than Korean ones. This allows songs and artists to be marketed to a wider audience around the world.
