Inhibitors:

- Developing and mantaining a search engine has become a game that requires huge investments that are hard to justify as the main form of income comes from selling advertising. After the tech bubble burst, not many people are willing to put money into that business model

- Concerns about non-paid content being influenced by the patronage of the paid advertising. Google and its AdWords gained a lot of attention and market share in recent years. The model has generated profits for the company and has caused others to offer the same. There is not enough disclousure about search rules for editorial and paid content results from search engines.

Paradigms:

- Information is power

- Commanding a large share of the market will allow search engines to develop other sources of income

- Search engines will evolve into intelligent search agents that will help increase productivity

Experts:

Various articles from periodicals were used

Timing:

Some milestones on the development of search engines (http://www.webreference.com/authoring/search_history/)… 1990 Archie. The program downloaded the directory listings of all the files located on public anonymous FTP (File Transfer Protocol) sites, creating a searchable database of filenames.

1991 Gopher indexed plain text documents

1993 World Wide Web Wanderer. Used to obtain URLs, forming the first database of Web sites called Wandex.

1993 ALIWEB was a search engine based on automated meta-data collection, for the Web

1993 Excite. It used statistical analysis of word relationships to aid in the search process. Within a year, Excite was incorporated and went online in December 1995. Today it's a part of the AskJeeves company.

1994 Yahoo. It started out as a listing of favorite Web sites. What made it different was that each entry, in addition to the URL, also had a description of the page. Within a year the Yahoo corporation was created.

1996 Inktomi started at UC Berkeley. In June of 1999 Inktomi introduced a directory search engine powered by "concept induction" technology

1997 Google was launched in 1997 by Sergey Brin and Larry Page as part of a research project at Stanford University. It uses inbound links to rank sites.

1998 MSN Search and the Open Directory were also started. The Open Directory, according to its Web site, "is the largest, most comprehensive human-edited directory of the Web. It is constructed and maintained by a vast, global community of volunteer editors." It seeks to become the "definitive catalog of the Web." The entire directory is maintained by human input.

2004 Paid advertising in search engines and relevance of results (appearing on the search engine as the first matches) have become so important that the of sector of Internet marketing known as search engine optimization (SEO) has grown in importance during 2004. Companies like Backbone Media, Inc. have experienced over 100% growth in 2004.(Market Wire, Nov. 01, 2004; BOSTON, Lexis Nexis). Recent Forrester studies have shown, especially in search engines like Google, that users respond and trust editorial listings more than pay per click or sponsored listing.
