AOL Time Warner

The largest media conglomerate in the world, Time Warner resulted from the merger of the publisher Time Inc. and the media company Turner Broadcasting Systems, Inc. in 1996. Time Inc. founded in 1922 primarily concentrated on magazines and books and in the 1950s moved into the broadcasting and entertainment industry, but in the 1970s announced that it was selling its broadcasting holdings and concentrating on cable television. In 1989 Time Inc. merged with Warner Communications Inc., which besides being a major motion-picture and television studio, was also one of the biggest U.S. music recordings producers and cable-television operators.

In January 2000 Time Warner merged with AOL (America Online) in a US$ 243.3 billion deal. Although AOL so far generated far less profit and turnover than Time Warner its quotation on the stock exchange was clearly higher, making Time Warner the junior partner (45 percent) in the new company. Through its merger with AOL, which is a major player in the online-business and owns several Internet-services like Compuserve, Netscape and Netcenter, the new media conglomerate could significantly enlarge its online presence and also complement its traditional media activities.

Acessing the Internet

The Net connections can be based on wire-line and wireless access technolgies.

Wire-line access

Wire-less access

copper wires

Satellites

coaxial cables

mobile terrestrial antennas

electric power lines

fixed terrestrial antennas

fiber-optic cables







Usually several kinds of network connections are employed at once. Generally speaking, when an E-mail message is sent it travels from the user's computer via copper wires or coaxial cables ISDN lines, etc., to an Internet Service Provider, from there, via fibre-optic cables, to the nearest Internet exchange, and on into a backbone network, tunneling across the continent und diving through submarine fibre-optic cables across the Atlantic to another Internet exchange, from there, via another backbone network and across another regional network to the Internet Service Provider of the supposed message recipient, from there via cables and wires of different bandwidth arriving at its destination, a workstation permanently connected to the Internet. Finally a sound or flashing icon informs your virtual neighbor that a new message has arrived.

Satellite communication

Although facing competition from fiber-optic cables as cost-effective solutions for broadband data transmission services, the space industry is gaining increasing importance in global communications. As computing, telephony, and audiovisual technologies converge, new wireless technologies are rapidly deployed occupying an increasing market share and accelerating the construction of high-speed networks.

Privatization of satellite communication

Until recently transnational satellite communication was provided exclusively by intergovernmental organizations as Intelsat, Intersputnik and Inmarsat.

Scheduled privatization of intergovernmental satellite consortia:

Inmarsat

1979

158 nations (all members of the International Maritime Organization)

privatized since 1999

Eutelsat

1985

Nearly 50 European nations

2001



When Intelsat began to accumulate losses because of management failures and the increasing market share of fiber-optic cables, this organizational scheme came under attack. Lead by the USA, the Western industrialized countries successfully pressed for the privatization of all satellite consortia they are members of and for competition by private carriers.

As of February 2000, there are 2680 satellites in service. Within the next four years a few hundred will be added by the new private satellite systems. Most of these systems will be so-called Low Earth Orbit satellite systems, which are capable of providing global mobile data services on a high-speed level at low cost.

Because of such technological improvements and increasing competition, experts expect satellite-based broadband communication to be as common, cheap, and ubiquitous as satellite TV today within the next five or ten years.
