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
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
Scheduled privatization of intergovernmental satellite consortia:

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.

With the rapid growth of the Internet and its audience advertisers now have a new medium at their disposal. The placement of the first banner ads in 1994 marks the birth of Internet advertising. Although the advertising industry at first hesitated to adopt the new medium, two facts brushed away their doubts:
Migrating Television Audiences: The increased use of the Internet led people to redistribute their time budget. Whereas some cut down on eating and sleeping, more than a third reduced watching television and instead uses the WWW.
Interesting Internet Demographics: While methodologies and approaches of research organizations studying the demographic composition of the Internet vary, the findings are relatively consistent: Internet users are young, well educated and earn high incomes.
Considering those findings, the Internet in the first place seems to become inevitable to be included in media planning, as part of the audience shifts from TV to the WWW, and secondly, because demographics of the Internet user population are irresistible for marketers.

Invented by Joseph Marie Jacquard, an engineer and architect in Lyon, France, punch cards laid the ground for automatic information processing. For the first time information was stored in binary format on perforated cardboard cards. In 1890 Hermann Hollerith used Joseph-Marie Jacquard's punch card technology to process statistical data collected during the US census in 1890, thus speeding up US census data analysis from eight to three years. Hollerith's application of Jacquard's invention was used for programming computers and data processing until electronic data processing was introduced in the 1960's. - As with
Paper tapes are a medium similar to Jacquard's punch cards. In 1857 Sir Charles Wheatstone used them for the preparation, storage, and transmission of data for the first time. Through paper tapes telegraph messages could be stored, prepared off-line and sent ten times quicker (up to 400 words per minute). Later similar paper tapes were used for programming computers.
1809
With Samuel Thomas Soemmering's invention of the electrical telegraph the telegraphic transmission of messages was no longer tied to visibility, as it was the case with smoke and light signals networks. Economical and reliable, the electric telegraph became the state-of-the-art communication system for fast data transmissions, even over long distances.

The telephone was not invented by Alexander Graham Bell, as is widely held, but by Philipp Reiss, a German teacher. When he demonstrated his invention to important German professors in 1861, it was not enthusiastically greeted. Because of this dismissal, he was not given any financial support for further development.
And here Bell comes in: In 1876 he successfully filed a patent for the telephone. Soon afterwards he established the first telephone company.
