Any way to find out where footage was used?

I just sold my first video and am curious if there's any way to find out who bought it or where/how it was used? I'm still learning my way around video and Pond5. Thanks!

The only way to know who bought or where the footage is used is if you or someone you know sees your footage and tells you.
None of the sites will tell us who buys the footage.
Since maybe 2000 of my videos is of me or my wife (or both )
I get told from friends almost weekly that they see us on the television or YouTube videos.

Thanks for the response, and very cool that you and your wife get spotted so often!
