The first recorded use of the term spyware occurred on October 17, 1994 in a Usenet post that poked fun at Microsoft’s business model. Spyware later came to refer to espionage equipment such as tiny cameras. However, in early 2000 the founder of Zone Labs, Gregor Freund, used the term in a press release for the ZoneAlarm Personal Firewall. ^[1] Since then, computer-users have used the term in its current sense.

In early 2000, Steve Gibson of Gibson Research realized that advertising software had been installed on his system, and he suspected that the software was stealing his personal information. After analyzing the software he determined that they were adware components from the companies Aureate (later Radiate) and Conducent. He eventually rescinded his claim that the ad software collected information without the user’s knowledge, but still chastised the ad companies for covertly installing the spyware and making it difficult to remove.

As a result of his analysis in 2000, Gibson released the first anti-spyware program, OptOut, and many more software-based antidotes have appeared since then. ^[1] International Charter now offers software developers a Spyware-Free Certification program. ^[2]

According to a November 2004 study by AOL and the National Cyber-Security Alliance, 80% of surveyed users’ computers had some form of spyware, with an average of 93 spyware components per computer. 89% of surveyed users with spyware reported that they did not know of its presence, and 95% reported that they had not given permission for the installation of the spyware. ^[3]

E-mail spam is by far the most common form of spamming on the internet. It involves sending identical or nearly identical unsolicited messages to a large number of recipients. Unlike legitimate commercial e-mail, spam is generally sent without the explicit permission of the recipients, and frequently contains various tricks to bypass e-mail filters. Modern computers generally come with some ability to send spam. The only necessary added ingredient is the list of addresses to target.

Spammers obtain e-mail addresses by a number of means: harvesting addresses from Usenet postings, DNS listings, or Web pages; guessing common names at known domains (known as a dictionary attack); and “e-pending” or searching for e-mail addresses corresponding to specific persons, such as residents in an area. Many spammers utilize programs called web spiders to find e-mail addresses on web pages, although it is possible to fool the web spider by substituting the “@” symbol with another symbol, for example “#”, while posting an e-mail address.

Many e-mail spammers go to great lengths to conceal the origin of their messages. They might do this by spoofing e-mail addresses (similar to Internet protocol spoofing). In this technique, the spammer modifies the e-mail message so it looks like it is coming from another e-mail address. However, many spammers also make it easy for recipients to identify their messages as spam by placing an ad phrase in the From field—very few people have names like “GetMyCigs” or “Giving away playstation3s”!

Among the tricks used by spammers to try to circumvent the filters is to intentionally misspell common spam filter trigger words. For example, “viagra” might become “vaigra”, or other symbols may be inserted into the word as in “v/i/a/g./r/a”. The human mind can handle a surprising degree of corruption, but sometimes this tactic can backfire, rendering a message illegible. ISPs have begun to use the misspellings themselves as a filtering test.

The most dedicated spammers—often those making a great deal of money or engaged in illegal activities, such as the pornography, casinos and Nigerian scammers—are often one step ahead of the ISPs. Reporting them to your ISP may help block less sophisticated spammers in the future.

So-called “spambots” are a major producer of e-mail spam. The worst spammers create e-mail viruses that will render an unprotected PC a “zombie computer”; the zombie will inform a central unit of its existence, and the central unit will command the “zombie” to send a low volume of spam. This allows spammers to send high volumes of e-mail without being caught by their ISPs or being tracked down by antispammers; a low volume of spam is instead sent from many locations simultaneously. Many consumer-level ISPs (Earthlink, for example) stop spambots by blocking the SMTP port (port 25), although there are some users who make legitimate use of it.

SEO began in the mid-1990s, as the first search engines were cataloging the early Web. Initially, all a webmaster needed to do was submit a site to the various engines which would run spiders, programs to “crawl” the site, and store the collected data. The search engines then sorted the information by topic, and served results based on pages they had spidered. As the number of documents online kept growing, and more webmasters realized the value of organic search listings, so popular search engines began to sort their listings so they could display the most relevant pages first. This was the start of a search engine versus webmaster game that continues to this day.

At first search engines were guided by the webmasters themselves. Early versions of search algorithms relied on webmaster-provided information such as category and keyword meta tags. Meta tags provided a guide to each page’s content. When some webmasters began to abuse meta tags, causing their pages to rank for irrelevant searches, search engines abandoned their consideration of Meta tags and instead developed more complex ranking algorithms, taking into account factors that were more diverse, including:

• Text within the title tag
• Domain name
• URL directories and file names
• HTML tags: headings, bold and emphasized text
• Keyword density
• Keyword proximity
• Alt attributes for images
• Text within NOFRAMES tags

By relying so extensively on factors that were still within the webmasters’ exclusive control, search engines continued to suffer from abuse and ranking manipulation. In order to provide better results to their users, search engines had to adapt to ensure their SERPs showed the most relevant search results, rather than useless pages stuffed with keywords by unscrupulous webmasters. This led to the rise of a new kind of search engine.

In ancient times the most common form of advertising was “word of mouth”. However, commercial messages and election campaign displays were found in the ruins of Pompeii. Egyptians used papyrus to create sales messages and wall posters. Lost-and-found advertising on papyrus was common in Greece and Rome. Wall or rock painting for commercial advertising is another manifestation of an ancient media advertising form which is present to this day in many parts of Asia, Africa, and South America. For instance, tradition of wall paintings may be traced back to India rock-art paintings that goes back to 4000 BC, see Bhatia 2000: 62-68 on the evolution of wall advertising. As printing developed in the 15th and 16th century, advertising expanded to include handbills. In the 17th century advertisements started to appear in weekly newspapers in England.

These early print ads were used mainly to promote books (which were increasingly affordable) and medicines (which were increasingly sought after as disease ravaged Europe). Quack ads became a problem, which ushered in regulation of advertising content.

As the economy was expanding during the 19th century, the need for advertising grew at the same pace. In America, the classified ads became popular, filling pages of newspapers with small print messages promoting all kinds of goods. The success of this advertising format led to the growth of mail-order advertising. In 1843 the first advertising agency was established by Volney Palmer in Philadelphia. At first the agencies were just brokers for ad space in newspapers, but by the 20th century, advertising agencies started to take over responsibility for the content as well.

The 1960s saw advertising transform into a modern, more scientific approach in which creativity was allowed to shine, producing unexpected messages that made advertisements interesting to read. The Volkswagen ad campaign featuring such headlines as “Think Small” and “Lemon” ushered in the era of modern advertising by promoting a “position” or “unique selling proposition” designed to associate each brand with a specific idea in the reader or viewer’s mind.

Today, advertising is evolving even further, with “guerrilla” promotions that involve unusual approaches such as staged encounters in public places, giveaways of products such as cars that are covered with brand messages, and interactive advertising where the viewer can respond to become part of the advertising message.
