ZDNET

ZDNET is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand ZDNET rather than just read about it. In short: ZDNET is a business technology news website owned and operated by Ziff Davis, which originally founded the brand on April 1, 1991, as its general interest technology portal. It eventually evolved into an enterprise IT-focused online publication.

Key takeaways

  • ZDNET belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect ZDNET to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of ZDNET from memory before moving on to harder problems.

Reference excerpt

ZDNET is a business technology news website owned and operated by Ziff Davis, which originally founded the brand on April 1, 1991, as its general interest technology portal. It eventually evolved into an enterprise IT-focused online publication. After being under the ownership of CNET Networks (2000–2008), CBS Corporation/ViacomCBS (2008–2020), and Red Ventures (2020–2024), ZDNET was reacquired by Ziff Davis in August 2024. CNET was included in the acquisition as well.

History

Beginnings: 1991–1995 ZDNET began as a subscription-based digital service called "ZiffNet" that offered computing information to users of CompuServe. It featured computer industry forums, events, features and searchable archives. Initially, ZiffNet was intended to serve as a common place to find content from all Ziff-Davis print publications. As such, ZiffNet was an expansion on an earlier online service called PCMagNet for readers of PC Magazine. Launched in 1988, PCMagNet in turn was the evolution of Ziff Davis' first electronic publishing venture, a bulletin board, which launched in 1985. In late 1994, Ziff-Davis expanded onto the World Wide Web under the name "ZD Net". Dan Farber, former editor-in-chief of PC Week and MacWeek, was named editor-in-chief of the property. By June 1995, the site was recording web traffic of 2.5 million pageviews per week. On June 20, 1995, Ziff-Davis announced the consolidation of its online information services under a single name, ZD Net. The service had grown its membership to 275,000 subscribers across six platforms: CompuServe, Prodigy, AT&T Interchange, The Microsoft Network, AppleLink and eWorld.

Early history: 1995–2000 By its fifth anniversary in 1996, the collective "ZD Net" brand—now on the Web, America Online, Microsoft Network and Prodigy—counted 300,000 subscribers and was named the second-highest grossing advertising site on the web. The site also expanded overseas: initially to France, Germany and the United Kingdom; later to China, Australia, Hong Kong, Italy, Korea, Malaysia, Russia, Spain, Taiwan and India. In 1997, the website—now the brand's flagship property—underwent another redesign that featured topical "channels" of content. It also marked the change in name from "ZD Net" to "ZDNet".

ZDNET News Two months prior, the company launched ZDNet News, or "ZDNN", the site's first dedicated section to original reportage. Among the journalists hired to staff the department were former Computer Shopper executive editor Charlie Cooper, San Jose Mercury News business editor Steve Hamm, PC Week Inside senior editor Bill Snyder, PC Week editor John Dodge, Computerworld editor Michael Fitzgerald and PC Week editorial director Jim Louderback. In 1996, the first dedicated advertising sales team began with the hiring of Ken Evans, formerly a CMP Media executive in New York, as Senior Director of Advertising Sales. The appointment of digital publishing executive Dan Rosensweig as ZDNet's first president capped a year of significant change for the brand. In 1998, ZDNet launched "Inter@active Investor", or ZDII, a spin-off website for investors that offered financial news and information on technology companies.

ZDTV On May 11, 1998, Ziff-Davis launched ZDTV as the first cable television channel and website to offer 24-hour programming about computing and the Internet. The venture, which was partly owned by Vulcan Enterprises, was supported with a staff of 170 and incorporated ZDNet content on its website, ZDTV.com. The channel would later become Tech TV. By the end of 1998, ZDNet was the dominant technology brand online. It led its closest rival, CNET, by a 26 percent margin and was the 13th most popular site on the Web, reaching 8.4 million users, or 13.4 percent of all users on the Web. The site would reach an additional 600,000 users within a year.

ZDNET the company In 1999, Ziff-Davis spun ZDNet off as a separate company and offered it as a tracking stock, ZDZ, to accompany the parent stock, ZD. An initial public offering raised $190 million, but the tracking stock was eliminated in early 2000 and revived as common stock. The new company soon acquired Updates.com, a software upgrade service. It was incorporated into the site's "Help Channel."

Consumer expansion In 1999, ZDNet also launched "Tech Life", a network of six consumer-focused tech sites intended to attract parents ("FamilyPC"), music listeners ("ZDNet Music"), gadget enthusiasts ("ZDNet Equip"), gamers ("ZDNet GameSpot") and basic users ("Internet Life" with Yahoo). It also launched "Computer Stew", a web-based comedy show about technology that featured John Hargrave and Jay Stevens, as well as the first ZDNet Holiday Gift Guide. On December 30, 1999, ZDNet launched a $25 million branding campaign in response to a $100 million advertising campaign launched by rival CNET. ZDNet's lead over the competition narrowed by 2000. Despite a record 10.7 million unique users in January, it managed only a 13 percent lead over the next competitor. By mid-2000, ZDNet had expanded to 23 countries in 14 languages on six continents.

The CNET years: 2000–2007 On July 19, 2000 CNET Networks (ZDNet's largest rival) announced that it would acquire ZDNET for about $1.6 billion. Some analysts thought that the merger of CNET and ZDNET would lead to redundancy in their product offerings, but research revealed that their target audiences had just 25 percent overlap. In 2001, Ziff Davis Media Inc. reached an agreement with CNET Networks Inc. and ZDNET to regain the URLs lost in the 2000 sale of Ziff Davis Inc, to Softbank Corp. In 2002, CNET Networks launched ZDNET sister site Builder.com, a site intended for enterprise software developers. On July 7, 2002, CNET Networks acquired Newmediary for its database of more than 30,000 enterprise IT white papers. ZDNET had integrated its services into its "Business & Technology" channel as early as January 2001.

Worked examples

Example 1 — a first encounter with ZDNET

Start with the simplest possible case. Write down what ZDNET claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to ZDNET before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about ZDNET ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of ZDNET

In research
ZDNET appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses ZDNET in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
ZDNET is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2008 mergers and acquisitions, 2020 mergers and acquisitions, American technology news websites, so understanding it makes those chapters shorter.
In everyday life
Look for ZDNET outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
