In the Wild - Getty Sales via Google Image Search
Every now and again (well i think i've done it twice now) i have a look and see if i can find any of my photos out there in the wild (online).
Using the google image search tool i've found the following 'commercial' uses online (i try and get a physical copy of printed stuff in books, mags, newpapers etc)
Stressing the 'commercial' use as the number of blogs and tumblrs and russian stock thiefs and other examples of people nicking stuff is too annoying and time consuming to even want to keep track of, my most popular stolen image has 372 pages of results on google image seach.
A few interesting uses (Squirrel pillow!) and a few good names to drop (CNN, Google, Mirror, Wall Street Journal)
