FirstPartner has some large “Market Maps” Available for download for several interesting markets like Augmented Reality, Location Services, and Mobile Media.  The maps are available as large-sized PDF’s in a watermarked free version and paid printable version.

To “buy” the free ones, you will have to supply a name and email.  The price is a bit high (65 €) but they would make nice wall-posters.
