Google trend on the word "microstock".  But you can do this on a bunch of keywords and the results are the same.  There is a dive since 2006 and if you click the forecast button it sort of stays level for the next year or two.

The interesting thing i find is if you click further down in regional interest and then choose by city.  you get Milan, New York, London, Madrid.  No LA, no Sydney, no Hong Kong.

Its all come down to fashion, models, the handshake and so on.  General stock is flooded.

I am working on a social media platform that is tied directly to a stock agency, share a photo and click to buy, contribute direct from social media.  Testing is being done for many reasons.  Complicated, but necessary for our research long term. 

Its a long story, but hopefully worth it in the end.

Why dont you tell us the whole long story....
