nice article though there is a very thin line between revealing the demand and creating demand ... just like inventing a PC (as author said) - before PC was invented the work was still going on w/o any problem, it was just taking little bit longer to finish .... so anything that saves time or money or energy (or all) will create demand automatically. Most of the time it is said that create/produce/develop something that people want it but sometime people dont even know that they need something (say computer). So when you create something that even people don't know that they need it then you're surely hitting a jackpot or you will fail terribly.

But sometime there are companies which just creates demand even though there is no need - for example soft drinks, alcohol, cigarette, most of the cosmetic products etc. There are solid arguments available that human being doesn't require these things but still multinational companies has created it to fill their pockets... but it doesn't do any good to human civilization. then is it even worth to create that kind of demands ??????
