Scholarly/academic journals, e.g. Journal of Marketing Research, may be peer-reviewed and provide research findings in a discipline.
Trade publications, like MarketingWeek and Adweek, inform or educate professionals in an industry or management function (e.g. marketing).
Popular magazines, like Time, Forbes, and newspapers like The Wall Street Journal, inform or entertain the general public.
If in doubt, ask your professor what kinds of periodicals they prefer that you to use for the assignment.
