Need some direction for my marketing class?

I need a research topic for my Marketing Management Class(Grad Program). I want something that would be interesting and fun to research. It could be a company, a company and their strategies, failures, sucess or it may just a concept in Marketing like brand recognition or something. Any Suggestion will be greatly appreciated. Thanks.

The long history of promotional marketing is interesting and still relevant. For example Pepsi put alot of money into getting "stuff" a few years ago and most major brands offer some type of item to keep their brand in front of consumers - McD has Happy Meals - containing a toy inside of a branded container, etc. Or focus on the recent Chinese made issues and how it affects marketing. Good Luck
Reply:It might be interesting to focus on the future of marketing, online marketing. Specifically affiliate networks and the ways that they have helped grow advertisers' business in the online space. It is legitimate, interesting and fast-paced direct marketing.
