The Dr. John Rutledge Blog on Technology, Policy, Economics, Investing, and Business has a comment on the recent rise in revenues of the various sectors of the economy:

[R]evenues were up more than 9% overall. And behind all the sectors you can find the driving force of rising productivity. The catch: continued productivity gains depend on huge impending investments in high-speed communications networks, yet Telecom sector earnings (+5.4%) are not growing fast enough to attract the capital to fund them. Mergers in the sector will help. Congress's intent to reform telecom law this year is badly needed. [Emphasis added.]
