Examples of Mainly Corporate Funded Think Tanks: Manhattan Institute

The Manhattan Institute, founded by William Casey, who later became President Reagan's CIA director, besides subsidies from a number of large conservative foundations has gained funding from such corporate sources as: The Chase Manhattan Bank, Citicorp, Time Warner, Procter & Gamble and State Farm Insurance, as well as the Lilly Endowment and philantropic arms of American Express, Bristol-Myers Squibb, CIGNA and Merrill Lynch. Boosted by major firms, the Manhattan Institute budget reached US$ 5 million a year by the early 1990s.

Bandwidth

The bandwidth of a transmitted communications signal is a measure of the range of frequencies the signal occupies. The term is also used in reference to the frequency-response characteristics of a communications receiving system. All transmitted signals, whether analog or digital, have a certain bandwidth. The same is true of receiving systems.

Generally speaking, bandwidth is directly proportional to the amount of data transmitted or received per unit time. In a qualitative sense, bandwidth is proportional to the complexity of the data for a given level of system performance. For example, it takes more bandwidth to download a photograph in one second than it takes to download a page of text in one second. Large sound files, computer programs, and animated videos require still more bandwidth for acceptable system performance. Virtual reality (VR) and full-length three-dimensional audio/visual presentations require the most bandwidth of all.

In digital systems, bandwidth is data speed in bits per second (bps).
