I am looking out for the same program. Here are some of my top picks.( In the states)
1. MS Integrated Marketing Communications- Northwestern(Medill)
2. MS Marketing-Columbia( This seems to be a more academic degree, you will find it within the doctoral program tab on their site)
3. MS Integrated Marketing- NYU(SCPS)
4. MS Marketing- Texas A&M(Mays)
5. MS Commerce(Marketing conc.)-University of Virginia(McIntire).
6. MS Marketing- Baruch College(CUNY)
7. MS Marketing- Rochester(Simon)
8. MS Marketing- Golden Gate University
Other MS degrees that might help you make the bridge into marketing and other business disciplines.
MS Industrial Administration- Purdue(Krannert).
MS Marketing Research-University of Georgia( only if ur interested in MR).
MS Global Management- Thunderbird
In the UK almost all the big business schools offer Msc degrees in marketing.
Hope this is useful.
