While the growth of the web over the past decade has been tremendous, it has been paralleled by incredible strides in the capability
of computer hardware. Without them, it would have been impossible for us to keep up. While the disks inside those duplos were on the
order of 10 gigabytes (GB), the drives we use today are on the order of 1 terabyte — one hundred times larger. To put this in perspective,
our fi rst major purchase when we started Google was an array of disk drives that we spent a good fraction of our life savings on and
took several car trips to carry. Today, I walked out of a store with a small box in my hand that stores more than all those drives and cost
about $100. Similarly, the processors available today are about 100 times as powerful as those we used in 1998.

by far the most complete collection of Usenet
articles ever assembled and a fascinating
fi rsthand historical account. At left is the oldest
