Some nice concise answers, makes me wish I was less of a rambler
One thing that is often forgotten when it comes to market research, is that data can be used to support your blog content or marketing. I think usually people assume that 'market research' should be just cold, scientific stats, but actually you can use it for a lot of 'softer' business needs as well.
Try googling the words: ' xxxx carried out a study respondents ' (where xxxx is a random company name of your choice - for example I just searched 'HP' and 'Rosetta Stone' from Google UK), you'll often find that these organisations are creating their own content through research. These organisations haven't carried out the research due to any scientific or strategic need and then decided to use it in a market campaign - they've carried out research specifically to use as a form of advertising.
