Is the whole world a big digg?

He drew attention to the fact that the business of high-tech products in the modern globalized world very much resembles the principle of Digg.com.
The manufacturer publishes a fresh model, users vote for it with their attention and wallet, buying it, as a result, little-known authors subside at the end of the rating, and promoted brands, in the case of a successful model, have it in the first lines of the demand rating, which leads to a further increase in this demand, and only rapid obsolescence due to the emergence of new models gradually discard the old ones tops. Poorly successful models, despite the brand's fame or advertising efforts, do not fall on the conventional “first page” and go off the stage much faster. Complete analogy with Digg, only the time period is not days, but years and voices are not virtual, but real money!
This also explains the fact that the number of brands in almost all product subgroups is constantly decreasing - there is little chance of survival outside the “first page”.
