The public relations industry, the same as advertising, is concentrated in the hands of few dominant firms. Still, the striking element about corporate public relations is that PR firms are tightly related to advertising companies. Nine out of the ten biggest international PR agencies have close ties with the advertising industry. Also, looking at the largest acquisitions involving U.S. PR firms from 1997 to 1999 it is apparent that money coming from advertising agencies has played an important role.

With many PR agencies sold to advertising companies, the advertising industry's influence further increases; enabling them to offer their clients not only advertising services, but also know-how in marketing, public opinion, crisis and issues management and political lobbying.

Public relations usually is associated with the influencing of public opinion. Therefore it has subsequently been linked with propaganda. Using one of the many definitions of propaganda "... the manipulation of symbols as a means of influencing attitudes on controversial matters" (Harold D. Lasswell), the terms propaganda and PR seem to be easily interchangeable.
Still many authors explicitly distinguish between public relations, advertising and propaganda. Unlike PR, which is often described as objective and extensive information of the public, advertising and propaganda are associated with manipulative activities. Nevertheless to treat public relations and propaganda as equivalents stands in the tradition of PR.
Also institutions like the

Although Web advertising becomes a significant portion of marketing budgets, advertisers are still unsure on how to unlock the potential of the Internet. Current findings show that:
- Consumer brands spend only a fraction of their advertising budget on on-line advertising.
- Technology companies spend five times more on advertising in the WWW.
- While banner campaigns are still popular, there is no standardized solution for on-line advertising.
- Ad pricing is based on CPM (costs per 1.000 visitors), rather than on results.
- Personalized targeting has not yet taken hold. Instead advertisers mainly target on content.
At the moment three dominant models are used for Internet advertising:
Destination Sites: They use entertainment, high production values and information to pull users in and bring them back again.
Micro Sites: Content sites or networks host small clusters of brand pages.
Banner Campaigns: Those include other forms of Web advertising like sponsorships.

The best known of the two-key cryptosystems developed in the mid-1980s is the Rivest-Shamir-Adleman (RSA) cryptoalgorithm, which was first published in April, 1977. Since that time, the algorithm has been employed in the most widely-used Internet electronic communications encryption program,
Aeneas Tacitus, a Greek military scientist and cryptographer, invented an optical communication system that combines water and beacon telegraphy. Torches indicated the beginnings and the ends of message transmissions while water jars were used to transmit the messages. These jars had a plugged standard-size hole drilled on the bottom side and were filled with water. As those who sent and those who received the message unplugged the jars simultaneously, the water drained out. Because the transmitted messages corresponded to water levels, the sender indicated by torch signal that the appropriate water level has been reached. It is a disadvantage that the possible messages are restricted to a given code, but as this system was mainly used for military purposes, this was offset by the advantage that it was almost impossible for outsiders to understand these messages unless they possessed the codebook.
With communication separated from transportation, the distant became near.
Tacitus' telegraph system was very fast and not excelled until
