As pointed out on their blog, Google noticed that You Tube viewers often follow-up with comments on where music from a video can be downloaded.  In response to this, Google has added “click-to-buy” links to the watch pages of thousands of You Tube partner videos, providing viewers the opportunity to act on their impulses.

Taking advantage of Internet user impulses isn’t unique to You Tube.  The iPhone has a brilliant application called Shazam.  If you’re ever in a situation where you’re listening to a song and are wondering what it is, hold your iPhone to the music and within seconds Shazam will tell you the artist, track and name.  A link to iTunes comes with it, allowing you to instantly purchase and download the track to your account.

It shouldn’t be surprising that the on-demand world provides opportunities to spend so frivolously, but it does make you wonder what the new opportunities will be, particularly in local search.  One opportunity might capitalize on the iPhones location awareness feature.  For example, if I use Google maps while walking around downtown, my proximity to restaurants might prompt their logos to populate the map; which then lead to coupons, say for $1 off Bloody Mary’s…wishful thinking I guess.
