Facebook for example could use pictures/videos of you and some advanced image analysis to construct such commercials automatically.
Taking it further, Facebook could use pictures/videos of your friends for other characters in the commercial. Logos for organizations that you have been associated with could be used as well (e.g., as stickers on that car).
When a client logged into his online account page, instead of showing "Banco do Brasil" (the bank's name) it'd show "Banco do <Client's-First-Name>" (Bruno's Bank -- if the client was called "Bruno", obviously).
A few hours after this seemingly clever personalization, there were _several_ national news sites talking about the new feature and how people were reacting to it: Some people couldn't understand this would only be visible to their session, they thought their name was showing up to everyone and wanted it removed ASAP.
Bottom line is: marketing acts should take into account how savvy the target audience is.
From the wired article, it looks like there were a number of legal issues with reusing photos without permission http://blogs.law.harvard.edu/infolaw/2007/11/08/facebook-soc... not to mention it's kind of creepy.
b.) The impact would be one of novelty, viewers wouldn't pay any attention to what the advert was trying to sell.
c.) Why bother, advertising is already able to sell products without placing the viewer inside the advertisements
a.) It's trivial to make it look good in fact it have been for quite some time.
b.) The impact is normally pretty big exactly because people pay attention once their friends or themselves are involved.
c.) Advertising as you seem to refer to it doesn't work nearly as well. Why do you think adwords work? They work because they communicate better by being closer to what you care about.
I shall see if I can make a list of examples but there is tons of great great examples looking stunning and having a huge impact.
On the bad-end, you see a mostly-accurate copy/paste of your head in a random expression slapped onto a car. On the good-end, you start fighting with the uncanny valley[1], and people start rejecting it because there's just something off about it. Then you've got people who won't know how you did it and will freak, as caioromao points out.
Will it happen eventually? I'd say absolutely, definitely. Minority Report shows a half-decent means of doing this, loathe as I am to cite sci-fi movies as future predictors. But doing it correctly, at all times, will take far more sophisticated visual analysis tools than we have right now.
The ad was a site http://www.capturehumans.com , which pulled your Facebook picture and pictures of your friends. The site then showed a short video on the origins of the vampiric plague, with you as Patient Zero. Your friends showed up as other early vampires or as humans to capture.
The site isn't loading for me now, but this description gives this idea: http://www.movieviral.com/2009/12/15/daybreakers-gets-a-vira...
