Madonna on Late Show with David Letterman
Late Night with David Letterman was a nightly hour-long comedy talk show on NBC that was created and hosted by David Letterman. It premiered in 1982 as the first incarnation of the franchiseLate Night and went off the air in 1993, after Letterman left NBC and moved to Late Show on CBS. Late Night with Conan O'Brien then filled the time slot. As of March 2, 2009, the slot has been filled by Late Night with Jimmy Fallon. It will be filled by Seth Meyers in the spring of 2014, after Fallon becomes host of The Tonight Show.
When Madonna appeared on Late Show with David Letterman on March 31, 1994, her coarse language, including thirteen uses of the word "fuck", made the episode the most censored in American network television talk-show history; it also resulted in some of the highest ratings of Letterman's late-night career.
Madonna's language and behavior—which was provocative, seemingly random at times, full of double entendres, and ended with a refusal to leave the set—caused a large public controversy. The Federal Communications Commission received numerous complaints, echoing Letterman's (sarcastic) remarks that "people don't want strong language in their homes on late night television".

In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.
Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
