Commercial vs. Independent Content: Human and Financial Resources

Concerning their human and financial resources commercial media and independent content provider are an extremely unequal pair. While the 1998 revenues of the world's leading media conglomerates (AOL Time Warner, Disney, Bertelsmann, Viacom and the News Corporation) amounted to US$ 91,144,000,000 provider of independent content usually act on a non-profit basis and to a considerable extent depend on donations and contributions.

Also the human resources they have at their disposal quite differ. Viacom for example employs 112,000 people. Alternative media conversely are mostly run by a small group of activists, most of them volunteers. Moreover the majority of the commercial media giants has a multitude of subsidiaries (Bertelsmann for instance has operations in 53 countries), while independent content provider in some cases do not even have proper office spaces. Asked about their offices number of square meters Frank Guerrero from RTMark comments "We have no square meters at all, because we are only on the web. I guess if you add up all of our servers and computers we would take up about one or two square meters."

The 17th Century: The Invention of the First "Computers"

The devices often considered the first "computers" in our understanding were rather calculators than the sophisticated combination of hard- and software we call computers today.

In 1642 Blaise Pascal, the son of a French tax collector, developed a device to perform additions. His numerical wheel calculator was a brass rectangular box and used eight movable dials to add sums up to eight figures long. Designed to help his father with his duties, the big disadvantage of the Pascaline was its limitation to addition.

Gottfried Wilhelm von Leibniz, a German mathematician and philosopher, in 1694 improved the Pascaline by creating a machine that could also multiply. As its predecessor Leibniz's mechanical multiplier likewise worked by a system of gears and dials. Leibniz also formulated a model that may be considered the theoretical ancestor of some modern computers. In De Arte Combinatoria (1666) Leibniz argued that all reasoning, all discover, verbal or not, is reducible to an ordered combination of elements, such as numbers, words, colors, or sounds.

Further improvements in the field of early computing devices were made by Charles Xavier Thomas de Colmar, a Frenchmen. His arithometer could not only add and multiply, but perform the four basic arithmetic functions and was widely used up until the First World War.
