Not so many years ago, if you wanted to sell your house you would run a classified ad in a newspaper. You paid by the line, so you wanted to keep it short. A typical ad would run something like this:

4Sale 4bdr 2ba colonial. wbf, eik, fdr, cac,2car garage, 1acre, $310K

To translate, the ad reads: For sale, a four bedroom colonial with two baths, a wood burning fireplace, and eat-in kitchen, a formal dining room and central air conditioning.

Anyone looking to buy a house today expects photos, and lots of them.
And more than likely, you're going to make your decision based on those photos.

But now, with the advent of universal broadband, more and more real estate is going to have video.
