Individualized Audience Targeting New opportunities for online advertisers arise with the possibility of one-to-one Web applications. Software agents for example promise to "register, recognize and manage end-user profiles; create personalized communities on-line; deliver personalized content to end-users and serve highly targeted advertisements". The probably ultimate tool for advertisers. Although not yet widely used, companies like Amazon.Com have already started to exploit individualized audience targeting for their purposes.

The 19th Century: First Programmable Computing Devices Until the 19th century "early computers", probably better described as calculating machines, were basically mechanical devices and operated by hand. Early calculators like the abacus worked with a system of sliding beads arranged on a rack and the centerpiece of Leibniz's multiplier was a stepped-drum gear design. Therefore Charles Babbage's proposal of the Difference Engine (1822), which would have (it was never completed) a stored program and should perform calculations and print the results automatically, was a major breakthrough, as it for the first time suggested the automation of computers. The construction of the Difference Engine, which should perform differential equations, was inspired by Babbage's idea to apply the ability of machines to the needs of mathematics. Machines, he noted, were best at performing tasks repeatedly without mistakes, while mathematics often required the simple repetition of steps. After working on the Difference Engine for ten years Babbage was inspired to build another machine, which he called Analytical Engine. Its invention was a major step towards the design of modern computers, as it was conceived the first general-purpose computer. Instrumental to the machine's design was his assistant, Augusta Ada King, Countess of Lovelace, the first female computer programmer. The second major breakthrough in the design of computing machines in the 19th century may be attributed to the American inventor Herman Hollerith. He was concerned with finding a faster way to compute the U.S. census, which in 1880 had taken nearly seven years. Therefore Hollerith invented a method, which used cards to store data information which he fed into a machine that compiled the results automatically. The punch cards not only served as a storage method and helped reduce computational errors, but furthermore significantly increased speed. Of extraordinary importance for the evolution of digital computers and artificial intelligence have furthermore been the contributions of the English mathematician and logician George Boole. In his postulates concerning the Laws of Thought (1854) he started to theorize about the true/false nature of binary numbers. His principles make up what today is known as Boolean algebra, the collection of logic concerning AND, OR, NOT operands, on which computer switching theory and procedures are grounded. Boole also assumed that the human mind works according to these laws, it performs logical operations that could be reasoned. Ninety years later Boole's principles were applied to circuits, the blueprint for electronic computers, by Claude Shannon.

Total copyright industries The total copyright industries encompass the "core copyright industries" and portions of many other industries that either create, distribute, or depend upon copyrighted works. Examples include retail trade (a portion of which is sales of video, audio, software, and books, for example), the doll and toy industry, and computer manufacturing.

Invention According to the WIPO an invention is a "... novel idea which permits in practice the solution of a specific problem in the field of technology." Concerning its protection by law the idea "... must be new in the sense that is has not already been published or publicly used; it must be non-obvious in the sense that it would not have occurred to any specialist in the particular industrial field, had such a specialist been asked to find a solution to the particular problem; and it must be capable of industrial application in the sense that it can be industrially manufactured or used." Protection can be obtained through a patent (granted by a government office) and typically is limited to 20 years.
