"The Internet, too, has strong attributes of a public good, and has undermined the â€œprivate goodâ€ attributes of old media. Internet service providers obviously can exclude people, but the actual content -the values, the ideas- can be shared with no loss of value for the consumer. It is also extremely inexpensive and easy to share material. Sharing is built into the culture and practices of the Web and has made it difficult for the subscription model to be effective."
