Companies in this industry provide access to the Internet via wired or wireless connections. Major companies include AOL, AT&T, Comcast, and Verizon (all based in the US), as well as Nippon Telegraph and Telephone Corporation (Japan), Telecom Italia (Italy), and Telefónica (Spain).
Demand is driven by consumer and business requirements for information. The profitability of individual companies depends on efficient operations and good marketing. Big ISPs have economies of scale in operations, purchasing, and marketing. Small companies can compete successfully by operating in underserved markets or excelling in customer service.
Major products are Internet access, website design and hosting, and technical support services. Wired telecommunications carriers account for about 80 percent of industry revenue. Other providers include wireless and satellite telecommunications carriers, as well as companies that use telecommunications infrastructure owned by others. Internet access allows individuals or companies to connect to the Internet over ordinary and special telephone lines, cable, or wireless connections (including satellite). Website hosting allows users to have an address on the Internet (a website) by maintaining files on a specialized computer called a server, while website design and technical services involve designing and constructing websites and consulting on various communications and operations issues.
