<P> In May 2004, M&M's ran a Shrek 2 promotion to tie in with the movie's release . M&M's were offered "ogre - sized" (65% larger) in swamp / ogre colors . They were sold at many stores displayed in huge cardboard - cutout ogre displays . </P> <P> In the summer of 2005, Mars added "Mega M&M's" to the lineup . These candies, at 55% larger than the traditional M&M's, were a little smaller than the ogre - sized version . They were available in milk chocolate and peanut varieties . The colors for Mega M&M's were changed to less - bright colors, ostensibly to appeal to older consumers: teal (replacing green), beige (replacing orange), maroon (replacing red), gold (replacing yellow), blue - gray (replacing blue), and brown . </P> <P> In July 2006, Dark Chocolate M&M's reappeared in a purple package, followed in 2007 by Dark Chocolate Peanut M&M's . Also in 2006, the company piloted White Chocolate M&M's as a tie - in with their "Pirates of the Caribbean" promotion . The company also offered eight new flavors of M&M's via online sales, as well as at M&M's World locations: "All That Razz"; "Eat, Drink, & Be Cherry"; "A Day at the Peach"; "Orange - U-Glad"; "Mint Condition"; "AlmonDeeLicious"; "Nut What You Think"; and "Cookie Monster". Mars also released a "Crispy Mint" variety in Australia that year . </P> <P> Also in 2006, M&M's became the official chocolate of NASCAR . </P>

When did the light brown m&m go away
