Snow and ice during the wintertime has led to other means of transportation, such as sledges, skis and skates. This also led to different pastimes and sports being developed in the winter season as compared to other times of the year. Naturally, winter sports are more popular in countries with longer winter seasons.
While most winter sports are played outside, ice hockey, speed skating and to some extent bandy have moved indoors starting in the mid-20th century. Indoor ice rinks with artificial ice allow ice skating and hockey to be played in hot climates.
