In 2007, Masterfoods USA-- a division of Mars, Inc. -- spent $ 100 million advertising M&M's chocolate candies in "offline" media (AKA everything except the Internet).
That's actually a pretty standard expense for the top candy and chocolate manufacturers!
Meanwhile, the Five A Day campaign (advocating the consumption of at least five servings of fruits and vegetables a day) had a $4 million advertising budget to spread their message across the United States in 2004.
By the way, that campaign was relaunched in 2007 after 15 years under the name "More Matters."
Rather than focus on one set number, consideration is given to individual guidelines based on varying calorie levels (some people only require four servings a day, while others should be getting eleven.)
This campaign's annual advertising budget? $3.5 million.
