Because my wife has been a 26 year listing agent and I spent 10 years helping her list homes I tend to see the world, much of the time, as a listing agent. One phenomena that has always amazed me is the magic effect of giving the home seller a DVD with photos of their home on it.
For much of my 10 years as a listing agent we gave all our home seller clients a CD of their stills and the 6 or 8-360's that I shot to market their home. I'd make a mini-CD that was a Windows only auto-run CD that had the custom Virtual tour on it. I never did fully appreciate what the big deal was about these CDs were. One listing client we had was the chief technical guy for a marketing company that had the account for Nikon. He loved the 360s of his home and the CD that I gave him of it so much that he talked me into doing a movie about real estate photography for the now defunct Nikonforbusiness.com web site. He also wanted a copy of the CD for each one of his 4 children and a couple for his parents and his in-laws. A large percentage of our listing customers would similarly get worked up about having their home tour on a CD.
In about 2004 after alienating a number of our listing clients that were Mac only users, that wanted a CD but I couldn't deliver, I realized that putting this stuff on a CD was crazy. It made much more sense to create a DVD that anyone could play on any computer or even without a computer on a DVD player.
Nowadays it's really easy to create a play-anywhere DVD with iDVD on the Mac, Adobe Premier Elements on either the Mac or PC or Pro Show Gold for the PC. The great thing about a DVD is everyone knows what to do with them. The downside is if you make them yourself it takes a little extra time. But I find that with a little practice you can turn them out pretty fast. The basic process with iDVD and the other software, is you make a slide show from the full size stills that looks pretty good on a large screen TV. Also since more and more marketing involves video as well as stills and most of the world has a large screen TVs in their home, DVDs make even more sense.
The loser in this move to DVDs is viewing 360s. I talked to a reader recently that was stressed over the fact that he couldn't find a way to create a DVD that would show stills and 360s. Yes, to view 360s you pretty much need to do it in a browser which is different from viewing DVDs. But I think the benefits of using DVDs for this purpose far out weight the downsides.
The bottom line is that even though you may think a DVD with a bunch of stills on it shown as a slideshow is not a big deal, listing agents love them because home sellers love them so much. Even the home buyers like them. So even though these DVDs are not big money makers they have the magic to make happy customers. Consider them just for the happiness they create!
