how to find out where competitors advertise online?

[jasonindus]

someone recently asked me if there is a way to find out what your competitors are doing in terms of online advertising. they mentioned that in print and offline there is a system called MMS.

Does anyone know of a either a system used to find out about online or can perhaps suggest their own method to researching competitors?

I usually google the competitors name and include the keyword 'advertising' and maybe i'll find an article or case study written by its advertising agency. although the results might not include anything that they've done online.
