This article came from Bloomberg Businessweek and features data from Information Resources Inc. (IRI), a consumer-market research vendor. They gathered their data from various kinds of stores that carried candy for one year and kept track of sales. This was a very quantitative research study and I think that it would have been nice to add a more regional theme. For example, the study told the reader that M&Ms are the most popular candy in America, but it did not tell the reader which part of America. If M&Ms were to only be popular in the south, then this would be helpful information for marketers to have.
