Voice calls were carried separately from data traffic, and e-mail required arcane commands and was used mostly at universities. The federal government had recently deregulated telecommunications and opened it to competitors. Deregulation opened voice and data networks to new competitors. These competitors competed with established providers for subscribers by offering lower prices. This competitio
