Situation comedies originated in the United States, but today they are some of the most popular programs around the world.The sitcom that revolutionized television in the 1950s in the United States was I Love Lucy, starring Lucille Ball and her husband, Cuban band leader and sometime actor,Desi Arnaz. It was the first seripted program ever to be performed in front of a studio audience,and to be recorded rather than broadcast live. I Love Lucy set the pattern for situation comedies for years to come. Ball and Arnaz played a married couple similar to themselves,but Lucy always got involved in crazy,comic situation.
