An online catalog can often expand to whatever amount of information is needed for a buying decision on any item. It can be downloaded on a floppy disk and given to a friend with no modem. Achieving big volume online often requires a big investment. The products and services offered must fit online's capabilities. Creating a good online catalog takes know-how and work.
Most online catalogs have small volumes versus the effort involved.
Even the best online catalogs fail without effective promotion. An online catalog doesn't seem user-friendly to many older people or women. It's not convenient to carry and read an online catalog from time to time, as many people peruse print catalogs. In addition, an online catalog can't show most PC owners a large number of high-resolution color pictures like a glossy print catalog or provide the color action of a video catalog. Each network encourages subscribers to log on to the catalog.
