CMT Big 4-0 was a series of music specials that ran sporadically on CMT from 2001 to 2002, each highlighting a specific theme across five episodes. Each episode was an hour hosted an influential member of the country music scene such as Cyndi Thomson and Keith Urban or regular CMT presenters like Tara McNamara. The specials were comprised chiefly of music videos aside from the presenter segments, and all of the videos held common themes like romance, or the "The First Time" special which featured the first video of some of country music's biggest stars. The hour segments are divided up to cover their own separate theme, from different artists to duets or time frames such as videos only released during the 1990s. The specials were often scheduled to release around specific events like award shows, anniversaries, or holidays like Valentine's Day and New Year's Eve with a theme that appropriately matched the corresponding event.
