Even back in the early days of the Internet (1990), many companies committed to more Internet Transit than they needed to obtain the lower unit price. They were then free to sell the excess to others to reduce their average unit cost (see Figure 3‑6).
Museums and small community colleges would formally or informally group-buy Internet access. Since Internet operations was never their primary activity, the customer support available to customers was minimal. Still, this tactic was used to lower the aggregate cost of transit.
