Paper driven processes are being reengineered to capture the benefits of doing business electronically. Businesses are implementing electronic commerce (EC or E- Commerce) to meet the imperatives of an increasingly competitive world. 1.2 What is Electronic Commerce? Electronic Commerce has unleashed yet another revolution, which is changing the way business buy and sell products and services. It is associated with buying and selling of information, products and services over computer communication networks. E-Commerce (EC) helps conduct traditional commerce through new ways of transferring and processing information, since it is information which is at the heart of any commercial activity. Information is electronically transferred from computer to computer, in an automated way. This has, in fact, transformed the way organizations operate. E-Commerce refers to the paperless exchange of business information using Electronic Data Interchange, Electronic Mail, Electronic Bulletin Boards, Electronic Funds Transfer and other network-based technologies. It not only automates manual processes and paper transactions, but also helps organizations have started conducting EC over the Internet, the network of networks. The Internet has given yet another boost to E-Commerce because it is a low-cost alternative to the proprietary networks. E-Commerce standards are, however, under development. The more well known Electronic Data Interchange (EDI), the inter- organizational exchange of business documentation in structured, machine processable from over computer communication networks, is still the dominant part of E-Commerce. Information gathering, processing, manipulating and distributing is common to trade and commerce, no matter what the commodity or service is that is being exchanged. Today, it is the velocity of information processing and dissemination which determines the speed of real commerce. Computers and networks, by virtue of their great speed, are creating electronic marketing with the potential to be more efficient in finding and interacting with customers, communication with trading partners and developing new products and markets. On the one hand, Local Area Networks (LANs), and enterprise wide intra-networks have resulted in raising expectations for data access, communications and productivity throughout Centre for Information Technology and Engineering, Manonmaniam Sundaranar University 3 E-Commerce Concepts and Application Design the business world. On the other, low-cost high-speed open networks interconnected as a single network, commonly known as the Internet, have kept pace with the requirements through the establishment of National Information Infrastructures, with high-speed National Information Highways being their main backbones. Widespread access to network communication tools including electronic mail awareness of the commercial potential of the Internet. While the Internet has already been successfully used for marketing, advertising and some commerce, much of its technical potential remains to be commercially harnessed. EDI is still the proven application for E-Commerce, although it is only one of the ways of doing electronic commerce. 1.3 Benefits of Electronic Commerce Electronic Commerce is the business environment in which information for the buying selling and transportation of goods and services moves electronically. Electronic Commerce (EC) includes any technology that enables a company to do business electronically. Some of the direct benefits of Electronic Commerce are: • Improves Productivity • Cost Savings • Streamlined Business Processes • Better Customer Service • Opportunities for

    To Our Stockholders, Partners, Employees and the eBay Community: A year in review 1999 was a historic year for eBay, ®lled with astonishing growth and rapid change. We began the year with 2.2 million users, a vibrant community about the size of Portland, Oregon and ended the year with over 10 million con®rmed registered usersÐmore than Michigan, the eighth largest state in the country. And that phenomenal growth re¯ected itself in every measure of our business: the number of items listed in 1999 totaled 129.6 million compared to 33.7 million in 1998. In the fourth quarter of 1999, every two tenths of a second, someone, somewhere was listing an item for sale on eBay Ð that translates to $113 dollars of gross merchandise sales per second. And, most impressive, gross merchandise sales grew an astounding 276 percent from $745 million in 1998 to $2.8 billion in 1999. During 1999, our users generated more economic activity on eBay than on any other consumer e-commerce site. Underlying this strength is the incredible popularity of the site. In 1999, eBay became one of the most recognizable Internet brands around the world, with numerous mentions in the media, business press and television. eBay was featured in such high pro®le publications as Forbes, the Washington Post and Time Magazine. In Time magazine, eBay was voted number one in their ``Best of 1999'' in the Cybertech area. eBay also continues to be mentioned on television shows including ``Who Wants to be a Millionaire?'', ``The Simpsons'', ``The Tonight Show'', ``Suddenly Susan'', ``Sports Night'' and of course, ``David Letterman's Top Ten List''.

  • THE LICRA V. Yahoo! CASE and the REGULATION of ONLINE CONTENT in the WORLD MARKET
    A RETURN TO LILIPUT: THE LICRA v. YAHoo! CASE AND THE REGULATION OF ONLINE CONTENT IN THE WORLD MARKET By Marc H. Greenberj ABSTRACT Over the past three years, a see saw battle has raged in Paris, France and in the heart of Silicon Valley in Santa Clara County, California, over the regulation of content on the Internet. The arena for this battle is the case of LICRA v. Yahoo!, which pits two non-profit human rights groups in France against giant Internet search engine and information portal Yahoo!, Inc. ("Yahoo"). The issues are (1) whether Yahoo may be prosecuted in France under French law for maintaining both auction sites that sell Nazi-related items and information sites promoting Nazi doctrine and (2) whether U.S. courts should enforce the resulting judgment. The first section of this Article presents the laws governing Internet content providers and the jurisdictional regime that gave rise to this see saw battle. The second section examines a series of court proceedings. The first two proceedings in France in 2000 resulted in a French court order directing Yahoo to add geo-location filtering software to its servers in Santa Clara. The subsequent California district court litigation filed in 2001 resulted in summary judgment for Yahoo. This judgment is on appeal. The third and final section explores the global implications of the French and U.S. proceedings. The section concludes that the international community should restructure certain principles governing international jurisdiction in Internet cases and adopt shared guidelines on online content available to the world market. These changes would promote the principle of international comity while allowing the Internet to retain most of its unique, borderless nature.

  • Why the Survivors Survived: Examining The
    WHY THE SURVIVORS SURVIVED: EXAMINING THE CHARACTERISTICS OF ONLINE COMPANIES DURING THE DOT-COM ERA By Peyton Elizabeth Purcell Submitted in partial fulfillment of the requirements for Departmental Honors in the Department of Finance Texas Christian University Fort Worth, Texas May 7, 2018 ii WHY THE SURVIVORS SURVIVED: EXAMINING THE CHARACTERISTICS OF ONLINE COMPANIES DURING THE DOT-COM ERA Project Approved: Supervising Professor: Dr. Paul Irvine, Ph.D. Department of Finance Cheryl Carithers, M.A. Department of English iii ABSTRACT This paper examines the dot-com bubble and the characteristics that enabled certain online companies to survive the crash in March of 2000. The purpose of the study was to examine financial data to understand what enabled certain companies to survive the dot- com bubble, while other companies with seemingly similar characteristics did not. The past few years sparked debate amongst investors on whether or not another bubble formed among technology companies such as Facebook, Amazon, Tesla, and Netflix. Currently, the world is in the middle of a technology boom. Investors care about the future success of technology companies that have a lot of promise baked into their stock price. My thesis attempts to examine the dot-com bubble that “burst” in March of 2000 and the companies that were able to withstand the crash until 2005. My results reveal a few conclusions about the companies in the dot-com era including (1) companies with negative earnings had a lower chance of survival; (2) companies with “.com” had a lower chance of survival; (3) companies with more volatile stock prices had a lower chance of survival; (4) companies that had higher advertising expenses had a lower chance of survival; (5) companies with higher shares outstanding had a higher chance of survival and; and (6) companies with pure online operations had a lower chance of survival.

  • Towards Digital Equality the U.S
    Towards Digital eQuality The U.S. Government Working Group on Electronic Commerce 2nd Annual Report, 1999 Foreword On that sunny, but cold January day when we took office nearly seven years ago, few could have foreseen the economic revival we have experienced. Fewer still would have predicted that this month we would be celebrating the creation of the 20 millionth new job. A central ingredient in our Nation’s virtuous cycle of economic reform has been the increased application of information technology to all facets of our business cycle from research and development to manufacturing, sales and marketing. All told, information technology has been responsible for about one third of real economic growth in the past few years. Our Administration has seen the birth and evolution of electronic commerce as a major factor in our economy and our lives. When we took office there were only 1.3 million computers connected to the Internet on a worldwide basis; today there are 56.2 million. (1) Seven years ago there were fewer than five million Americans using the Internet; today that number exceeds 100 million. (2) When we created the Electronic Commerce Working Group a mere three years ago the amount of commerce conducted over the Internet totaled less than $10 billion; now it is projected to exceed $1 trillion in the next few years. This transformation has been led by the private sector, but increasingly government policies and attitudes towards e-commerce have played an indispensable role in shaping the outcomes. Over the last few years, electronic commerce has become synonymous with the explosion of methods and applications of information technology.

  • Patent Activity in Bankrupt Technology Firms: an Empirical and Case-Based Study
    Patent Activity in Bankrupt Technology Firms: An Empirical and Case-Based Study Grant E. Moss Emory University, Goizueta Business School Masters of Business Administration Candidate June 1, 2010 Turnaround Management Association, 2010 Carl Marks Student Paper Competition Abstract: Intellectual property is a considerably valuable asset for technology companies, but managers often do not fully appreciate and extract value from those assets. In order to determine the perceived value of patents in the context of bankrupt technology firms, I analyzed the patent portfolios of 100 firms with the purpose of developing a better understanding of the management of intellectual property in times of distress. The result is that there is no clear prescription for effectively managing intellectual property, but a limited number of firms did creatively extract value from their intellectual property. 1 Contents I.

  • Assessment of Business-To-Business (B2B) E-Marketplaces' Performance
    2007:22 DOCTORAL T H E SI S Assessment of Business-to-Business (B2B) e-Marketplaces’ Performance Anne Engström Esmail Salehi-Sangari Luleå University of Technology Department of Business Administration and Social Sciences Industrial Marketing & e-Commerce Research Group 2007:22|: 02-544|: - -- 07⁄22 -- Assessment of Business-to-Business (B2B) e-Marketplaces’ Performance Anne Engström Esmail Salehi-Sangari Luleå University of Technology Department of Business Administration and Social Sciences Industrial Marketing & e-Commerce Research Group 2007 ABSTRACT Electronic marketplaces (e-marketplaces) are new business venues for buying, selling, and supporting customers, products, and services in many industries. The emergence of business-to-business (B2B) e-marketplaces has opened up opportunities for efficient online transactions between firms. While large capital investments were made in numerous B2B e-marketplace initiatives, a significant number of these firms ended up going bankrupt. Today, many e-marketplaces are still struggling to survive and are trying to understand the characteristics of viable business models and strategies for becoming successful. Research within this field is scarce and provides only fragmented insights into the area. Thus, the research problem of this thesis was designed to investigate holistically how the business performance of a B2B e-marketplace can be analyzed. Based on literature review and a pilot study, four research questions were developed and a theoretical framework was then created. A qualitative research approach, investigating six B2B e-marketplaces in Europe and the US, was adopted. Results from this study indicate that differences exist between B2B e- marketplaces in several aspects of their strategic position; thus, the existing taxonomy of B2B e-marketplaces can be questioned.
