Forbes 2000

I recently came across the Forbes 2000 list for the year 2008. And it was astonishing to see such a wide array of statistics piled up for corporations across the world. I wanted to make some observations. According to the list,
1. The company with the highest Market Cap was china's PetroChina
2. The technology company with the highest market cap was not Microsoft! But china's ChinaMobile.
3. The technology company with the largest revenue was AT&T.
4. WalMart still retained the number one spot for the highest revenue
5. Japan's Toyota had a similar revenue compared to GM, which it ousted as the the world's largest manufacturer of automobiles. What was striking was the ratio of the two's market cap. Toyota's Mcap was almost 13 times that of GM
