The Eurovision Song Contest, often simply called Eurovision, is an annual international song competition, with participants representing primarily European countries. Each participating country submits an original song to be performed on live television and radio, then casts votes for the other countries’ songs to determine the winner. At least 50 countries are eligible to compete as of 2018.

Based on the Sanremo Music Festival held in Italy since 1951, Eurovision has been broadcasting every year since its inauguration in 1956, making it the longest-running annual international television contest and one of the world’s longest-running television programs. It is also one of the most watched non-sporting events, with audience figures of between 100 million and 600 million internationally. It has been broadcast in several countries that do not compete, such as the United States, Canada, New Zealand, and China. Since 2000.
