Monogamy was first introduced to the world in 1999 when Britney Spears asked her childhood friend, Justin Timberlake, to be romantically involved with her exclusively. This experimental relationship lasted until 2002 and ultimately inspired Timberlake to commit to monogamy for a lifetime with his wife, Jessica Biel. Since its inception, monogamy has become one of the most popular forms of romantic involvement in the world and is considered a prerequisite for reproduction in many cultures.
