Internet Pricing and the History of Communications
Internet pricing and the history of communications Andrew Odlyzko AT&T Labs - Research [email protected] http://www.research.att.com/ amo Revised version, February 8, 2001. Abstract There are repeating patterns in the histories of communication technologies, including ordinary mail, the telegraph, the telephone, and the Internet. In particular, the typical story for each service is that quality rises, prices decrease, and usage increases to produce increased total revenues. At the same time, prices become simpler. The historical analogies of this paper suggest that the Internet will evolve in a similar way, towards simplicity. The schemes that aim to provide differentiated service levels and sophisticated pricing schemes are unlikely to be widely adopted. Price and quality differentiation are valuable tools that can provide higher revenues and increase utilization efficiency of a network, and thus in general increase social welfare. Such measures, most noticeable in airline pricing, are spreading to many services and products, especially high-tech ones. However, it appears that as communication services become less expensive and are used more fre- quently, those arguments lose out to customers’ desire for simplicity. In practice, user preferences express themselves through willingness to pay more for simple pricing plans. In addition, there is a strong “threshhold” effect to usage-sensitive billing. Even tiny charges based on utilization decrease usage substantially. In a rapidly growing market, it is in the service providers’ interest to encourage usage, and that argues for simple, preferably flat rate, pricing. Histori- cal evidence suggests that when service costs decrease, such arguments prevail over the need to operate a network at high utilization levels and to extract the highest possible revenues. -

INSIDE MICROSOFT (Part 2) 2/7/04 2:30 PM
07/15/96 INSIDE MICROSOFT (Part 2) 2/7/04 2:30 PM INSIDE MICROSOFT (Part 2) The untold story of how the Internet forced Bill Gates to reverse course (Continued from Part 1) BABY STEPS. In one breakout group, Allard tangled with Russell Siegelman, who was heading Marvel, the code name for what's now the Microsoft Network online service. Allard argued that instead of being proprietary, Marvel should be based on Web standards. Siegelman held his ground--and won. It was a decision that would later cost millions to reverse. Still, Net progress was made: TCP/IP would be integrated into Win95 and Windows NT, the version of Windows that runs network-server computers. The sales team was told to use the Web to dispense marketing information. The applications group agreed to give Word, the word-processing program, the ability to create Web pages. Next, Gates jumped deeper into the process by devoting much of his April Think Week--a semiannual retreat--to the Internet. His Apr. 16 memo, ``Internet Strategy and Technical Goals,'' contained the first signs of a growing corporate commitment. ``We want to and will invest resources to be a leader in Internet support,'' wrote Gates. It was a first step, albeit a measured one. ``I don't think he knew how much to bet yet,'' says Allard. But board member David F. Marquardt did: He recalls that he was ``amazed'' that Microsoft was putting so little into the Net. ``They weren't in Silicon Valley. When you're here, you feel it all around you,'' says Marquardt, a general partner at Technology Venture Investors in Menlo Park, Calif. -
In Re: Global Crossing, Ltd. Securities Litigation 02-CV-00910-Notice Of
UNITED STATES DISTRICT COURT SOUTHERN DISTRICT OF NEW YORK ________________________________________________ x IN RE GLOBAL CROSSING, LTD. : Case No. 02 Civ. 910 (GEL) SECURITIES LITIGATION : ________________________________________________ x NOTICE OF PROPOSED CLASS ACTION PARTIAL SETTLEMENT, MOTION FOR ATTORNEYS' FEES AND FAIRNESS HEARING IN CONNECTION WITH THE ANDERSEN SETTLEMENT If You Bought or Exchanged Global Crossing Ltd. Securities or Asia Global Crossing Ltd. Securities between February 1, 1999 and December 8, 2003, you might be a member of the class in this action entitling you to receive relief in connection with a partial settlement of the action. A federal court authorized this Notice. This is not a solicitation from a lawyer. ■ On July 7, 2005, a settlement between the plaintiffs and Arthur Andersen LLP (the “Settlement”) was preliminarily approved by the Court in the action captioned above. The Settlement partially resolves a lawsuit over whether the prices of common stock, convertible preferred stock and bonds of Global Crossing and Asia Global Crossing were artificially inflated as a result of alleged fraudulent misrepresentations and non-disclosures and violations of federal securities laws. ■ The Settlement provides for a Settlement Fund of approximately $25 million, less fees and costs. The amount to be distributed among the class members will be divided between Global Crossing and Asia Global Crossing securities purchasers, with Global Crossing securities purchasers getting 92% of the amount and Asia Global Crossing securities purchasers getting the remaining 8%. ■ As explained below, this is the third partial settlement in this lawsuit. If you qualify and have not filed a claim in either of the prior settlements and would like to submit one, you may do so. -

This began with point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of networks. In 1982 the Internet Protocol Suite (TCP/IP) was standardized and the concept of a world-wide network of fully interconnected TCP/IP networks called the Internet was introduced. -

SEC News Digest, 10-20-1999
SEC NEWS DIGEST Issue 99-202 October 20, 1999 RULES AND RELATED MATTERS ADOPTION OF UPDATED EDGAR FILER MANUAL A revised EDGAR Filer Manual and Form ID became effective on October 18. This new version of EDGAR and the EDGAR Filer Manual (Release 6.60) incorporates changes resulting from the decision by CompuServe, a sub-contractor to TRW (the developer of the EDGAR system), to discontinue its EDGAR services. These services include the Public Data Network (PDN) for transmission of filings to EDGAR, private mailboxes for receiving EDGAR Acceptance/Suspense notifications and Return Copies, the EDGAR company database, and the bulletin board. TRW has contracted with UUNET to provide EDGAR Private Mail and PDN Services. Although The EDGAR bulletin board and the EDGAR company database will no longer be available, filers may obtain similar information from our Web Site at www.sec.gov and the TRW/UUNET Web Site at www.trw-edgar.com. The Form ID, the Uniform Application for Access Codes to File on EDGAR, was also changed to reflect the change in the EDGAR private mail service. The basic TRW/UUNET service will include five hours of access and a mailbox for messages. There will be additional charges for larger mailboxes and connect time over the basic limit. Those filers who want to use the public data network for transmission to EDGAR, who want a private system (instead of the Internet) for receipt of acceptance/suspense messages, or who want an electronic returned copy of their filings must sign up for this service. To access their new mailboxes, filers will use a standard POP3 mail client. -

Baird* & Robert K. Rasmussen** ABSTRACT The law of corporate reorganizations is conventionally justified as a way to preserve a firm’s going-concern value: Specialized assets in a particular firm are worth more together in that firm than anywhere else. This paper shows that this notion is mistaken. Its flaw is that it lacks a well- developed understanding of the nature of a firm.
