Internet applications exploded in the late 90s. Many companies were set up to provide Web services. Young 15 year old whiz kids were developing mind boggling sites peddling all sorts of information. Communications companies had to find new technologies to provide high-speed access lines. Customers migrated from dial-up capable of 56 K bps speed to 1.544 M bps speed connections. The high-speed Internet services became available from the cable and the telephone companies. Now the Internet services are available on the Wireless network.
