Lets take a look at recent bandwidth speed history.
The chart below was published as part of a 1on1 Design e-Plus newsletter dated September 1999. Notice the bandwidth speed difference, not to mention the fact that we are including 14.4 and 28.8 modems in our 1999 graph. At the time there were a significant amount of users connecting at 14.4 and 28.8 speeds. Below is a updated chart for 2001. For both the 1999 and 2001 broadband charts, the mauve colored section of the bar represents a 5MB file download and the green section represents a 1MB e-mail attachment.
