The pay-per-call industry uses 900-number technology to market entertainment and information services. Once considered a business with enormous potential, the pay-per-call industry was hindered because it was tainted early on by scam artists who adopted the technology in large numbers. Increasingly, however, the legitimate pay-per-call industry is offering business-to-business and business-to-consumer services, and major corporations are turning to pay-per-call services to replace toll-free 800 number operations. Today, pay-per-call services include product information and support lines, stock market quotes, weather information, marketing, merchandising, consumer research, and customer services.
