Need numbers/chart to illustrate penetration of computers in business

Just hoping someone there already has a reference.  I've spent a while Googling to no avail.

I'm looking for something that would show how important computers (and the Internet) are to business in general today.

For instance, something like "it would take 10,000 accountants to replace the accounting functionality of a typical Fortune 500 company's computer system".

Or a chart of the amount of work (maybe in terms of transactions handled per day) done by computers over the past decade.

Stuff like that.

Obviously, I'm including all computers (mainframe to micro).

Any references?

Gates touts importance of business computers
By George Tibbits
Associated Press

      SEATTLE -- Information technology is the "digital nervous system" of any business, Microsoft Chairman Bill Gates told fellow executives Thursday.
      "No matter what business you are in, it's my claim that the excellence of that system determines your competitiveness," he said.
      Gates, who invited 100 chief executives for a two-day conference here on the value of information technology to business, also cautioned them not to underestimate the growing role computers will play in everyday life.
      While Gates made no overt sales pitch, he said corporations should give their "knowledge workers" the computers and software needed to perform a variety of tasks, a strategy obviously beneficial to Microsoft, the world's largest producer of personal computer software.
      Vice President Al Gore was to address the gathering.
      Among those attending were Paul Hazen, chairman and CEO of Wells Fargo and Co.; GTE chairman and CEO Charles R. Lee; Reed E. Hundt, chairman of the Federal Communications Commission; and Robert L. Crandall, chairman and CEO of AMR Corp., the parent of American Airlines.
      Reporters were not allowed in the sessions but were able to watch the speeches over closed-circuit television.
      Gates and his company have made a fortune developing software for individual personal computers. Not surprisingly, that continues to be Gates' vision of the future.
      In the marketplace, "the PC model has really won out" and has allowed both hardware and software development to go ahead at full speed, he said.
      He said the personal computer will become more important to businesses as the machines prove their ability to take on more demanding tasks. And he predicted more business transactions will be conducted over the Internet.
