Relations between South Korea and Latin America have been growing since the 1960s. In the past decade, South Korean companies such as LG Corporation and Samsung have established businesses in Latin America, which improved trade relations between the two regions. LG and Samsung also played a role in the spread of K-Pop to Latin America. K-Pop by LG was a yearly dancing competition sponsored by LG electronics in Colombia. K-Pop by LG took place from 2011 to 2013 during the months of October through December in Bogotá, Medellín, and Cali, three major cities in Colombia. Samsung was named the official sponsor for South Korean boy band Big Bang during their first worldwide concert tour in 2012, the Big Bang Alive Galaxy Tour. Big Bang performed in Lima, Peru, the only city in South America they visited as part of their Alive Galaxy tour, on November 14, 2012.

A karaoke box is a type of karaoke establishment commonly found in East Asia, Southeast Asia, South Asia, the United States and Canada. It originated in Japan, and is now popular worldwide, particularly in Asia. Karaoke boxes consist of multiple rooms containing karaoke equipment, usually rented out for a period of time. A typical karaoke box establishment contains 10–20 such rooms, that can be themed so that each room has a different feeling or can be a traditional karaoke box, as well as have a main karaoke bar area in the front. Karaoke box establishments often sell beverages, and sometimes food but sometimes the establishment offers free refreshments. Many people of all ages enjoy karaoke as a pastime in Japan, as it still has a huge influence in the Japanese music scene and it is also a place that can attract tourists as well. One blogger, who is a fan of karaoke, writes "...to sing karaoke is to embrace the moment that your love of song transcends your love of self." While people do go to and enjoy karaoke boxes with family and friends, people also go by themselves and are able to enjoy the comfort of performing in the room by themselves. There is also a different style of karaoke, the traditional type where the patrons sing in front of everyone that is also still offered in popular entertainment areas, rather than the private boxes.
