• It Adds Up (and U[, and Up) (NY Times, April 10, 2003)

  An analysis of government data by academic researchers over the last 25 years shows that from the 1920's through the 80's, the average household spent about 6 percent of its disposable income on "information and entertainment," a category embracing everything from newspapers and movies to telephone service, radios and television sets.

• "There's widespread agreement in the telecom industry that the allocated network costs on a per minute basis is about 2 cents. Sprint has won several RBOC wholesale LD contracts with bids of 1.25 cents per minute. Given that those prices include profit margin and non-network costs built in it, one can safely say that the long run incremental network cost of a minute is well below 1 cent."
