Paramount Home Entertainment and (from 2006 onward) CBS Home Entertainment have released all 11 seasons of Cheers on DVD in Region 1, Region 2 and Region 4. In the US, some episodes from the final three seasons appear on the DVDs with music substitutions. For example, in the episode "Grease", "I Fought the Law" was replaced even though its removal affects the comedic value of the scenes in which it was originally heard.
