Ms. Brown is a Chocolate M&M and is currently the newest main M&M character. Supposedly she is "the original milk chocolate" and has been M&M's chief chocolate officer for the past 70 years.
Ms. Brown was first hinted at in January of 2012 on the official M&M Facebook page. At this point in time only her silhouette was shown, and she was set to appear in an M&M ad during the Superbowl that aired on February 5th 2012. After that, she became one of the main M&M characters, often appearing in adverts alongside Red and Yellow.
M&M Packaging Edit
Strangely, Ms. Brown rarely appears on M&M packets, nor does she have her own flavour of M&M that she is known for. Ms. Brown has made a few rare package appearances except for on some seasonal packaging.
