Science fiction becomes reality in so many ways, as anyone who has been playing games or reading books long enough can tell. Now, in the U.S., crime fighting is taking the next technological step in advertising wanted criminals or missing people – digital billboards. Whereas wanted posters in the olden and golden days would require considerably effort to tack up and change often, a digital billboard has the advantage of being able to be programmed or changed on the fly.

It is obvious to see the benefit here. It's a double edged sword, of course, and sooner or later we'll probably see one of these digital billboards become hijacked and display something the FBI might not rather show. Still, it's rather fascinating, and shows a good application of newer technology. In an eerie way, however, it might remind you of moments from games or books in which Big Brother is peering down at you.
