One of the services that Curve12 offers is the creation of interactive CDs. In essence it's a website on a compact disc. The CD's are built to run on both PC and Mac computers.
Why not just send them to your website? With CD's you can put crisper, higher resolution images and videos without the delay of downloading. Everyone says they'll go to your site, but with a disc they have a constant reminder.
Some areas you may find the CD application usefull are: Portfolios, Music CD's (audio CD features can be incorperated along with interactive media), Demo Reels, Press Kits, Visual Presentations...
