Oversea sports are those that take place outside the home territory of their respective league or team. This includes international competitions like the Olympics and the FIFA World Cup. It also means that a professional athlete might choose to play abroad rather than staying at home and playing for a local club.

The earliest known oversea sports event took place in ancient Greece, when city states would travel to Olympia to compete in various games. This set a precedent for international sport, which today takes place in many countries.

As globalization increased, the world became more connected through technology, especially radio and later television, which allowed sports to be broadcast to a much wider international audience than ever before. This helped to increase interest and participation. The advent of commercial aspects to sport, such as sponsorship and merchandise, further increased the financial clout of the sport and gave formerly amateur athletes a more lucrative way of earning a living.

Today, top-tier sporting teams often travel to different parts of the world during pre-season to prepare for upcoming competitions and to promote their league, team, merchandise and sponsors. This has also been made more practical by the expansion of air travel. There are more overseas sport at 해외스포츠중계.

This is a two-way street, as the players in these visiting teams have also learned something about the game from their hosts. Whether it was the impact of touring Argentinian and Brazilian football teams in Europe in the 1920s, or the influx of American basketball players to European clubs in the 1930s, these visits have had a positive influence on both the visitors and their domestic counterparts. The same can be said for the recent arrival of eSports (electronic sports) to the mainstream.
