South Korea has a developed economy led by technology companies like Samsung and LG. Its culture, especially K-pop music and TV, has become widely popular throughout Asia and other parts of the world in a phenomenon called the "Korean Wave". Traditional Korean culture was influenced by China but Koreans believe their cuisine, language, and alphabet set them apart from other Asian cultures. Nearly half the population does not follow a particular religion, with Christianity and Buddhism each having about a quarter of adherents. Baseball and martial arts like taekwondo are popular sports in Korea.
