Many Super Bowl advertisements have become iconic and well-known because of their quality , unpredictability , humor , and use of special effects . In recent years , advertisers have also attempted to stand out from others by producing ads with cinematographic qualities , and ads that channel emotions and real-world issues . The use of celebrity cameos has also been common in Super Bowl ads , ranging from then-unknown personalities , to unexpected combinations of celebrities , such as a 2007 CBS network promo for '' Late Show '' that featured David Letterman and Oprah Winfrey — whom Letterman had conflicts with following a joke directed at her during the 67th Academy Awards , and a 2010 sequel that also included Jay Leno ( who was slated to return to its competitor , '' The Tonight Show '' , following a publicized conflict between NBC and Conan O'Brien )
