Back in the good old days of DOS, people who would not pay the price of name-brand software used shareware. If you liked the product, you were expected as a matter of honor to pay for it, and the prices were reasonable. Shareware was advertised in mailers and on neighborhood on-line bulletin boards. The shareware concept lives. Frequent nag screens remind the user.
Menus become more convenient to the registered user.
Extra goodies are often supplied upon payment. Some programs stop working after 30 days if not registered. Shareware is now listed on the Web. Each lists hundreds of products, ranging from clones of big-name software to some real oddballs. You can find a Beanie Baby database, a bartender's guide, antique appraisal forms, games, church and organization membership systems, genealogy programs, an on-screen planetarium, and thousands of others.
