What an ugly and awkward word. Corporatacracy. Basically it means the rule of corporations or government by corporation. Some people use "corporacracy" which gets rid of a syllable but I believe the other form may be more linguistically accurate.

CorpWatch has a little factsheet from 2001 but I bet it's still pretty accurate:

• Fifty-one of the world's top 100 economies are corporations.

• Royal Dutch Shell's revenues are greater than Venezuela's Gross Domestic Product. Using this measurement, WalMart is bigger than Indonesia. General Motors is roughly the same size as Ireland, New Zealand and Hungary combined.

• There are 63,000 transnational corporations worldwide, with 690,000 foreign affiliates.

• Three quarters of all transnational corporations are based in North America, Western Europe and Japan.

• Ninety-nine of the 100 largest transnational corporations are from the industrialized countries.

A good juxtoposition to the information on corporations above, CorpWatch also has a factsheet on the practice of "greenwashing". You can find numerous examples of this in advertising.

• BP, the world's second largest oil company and one of the world's largest corporations, advertised its new identity as a leader in moving the world "Beyond Petroleum." It touted its $45 million purchase of the largest Solarex solar energy corporation. But BP will spend $5 billion over five years for oil exploration in Alaska alone.

• Shell, the world's third largest oil company, continues its clever but misleading ad series "Profits or Principles" which touts Shell's commitment to renewable energy sources and features photos of lush green forests. But Shell spends a miniscule 0.6% of its annual investments on renewables. In true greenwash fashion, Shell's actions do not match its words.

• For Earth Day 2000, Ford Motor Company announced that all corporate brand advertising will have an environmental theme. It expects to spend as much on this greenwashing as it does to roll out a new line of cars, such as the global warming gas guzzler Ford Excursion.

• Monsanto, Dow, Dupont, Novartis, Zeneca, BASF and Aventis launched the "Council for Biotechnology Information," in April 2000. The Council will spend up to $250 million over 3-5 years to win public approval for genetically engineered foods under the slogan "Good Ideas Are Growing."
