Search Engine - Wikipedia

History

The concept of search engines dates back to the 1940s, when Vannevar Bush described an information retrieval system called the "memex". He envisioned a system that would allow users to access a vast amount of information from a single desk.

1990s: Birth of Search Engines

The first internet search engines predated the debut of the World Wide Web in December 1990. Archie, a search engine that searched content files, was launched on September 10, 1990. Veronica and Jughead, two other search engines, were developed in the early 1990s to search Gopher index systems.

2000s-Present: Post Dot-Com Bubble

By the 2000s, search engines had become a dominant force on the internet. Google Search became the most popular search engine and has remained so. Other search engines, such as Bing, Yandex, and Yahoo, have smaller market shares.

Approach

Search engines use various methods to crawl, index, and retrieve information from the web. They may use algorithms to rank search results, and some may provide specialized search features, such as image or video search.

Market Share

Google Search dominates the search engine market, with a global market share of around 90%. Bing, Yandex, and Yahoo have smaller market shares, ranging from 4% to 1%.

Search Engine Bias

Search engines have been criticized for their bias towards certain types of content or websites. This bias can be influenced by factors such as the algorithm used to rank search results, the quality of the search engine's crawling process, and the cultural and linguistic biases of the search engine's developers.

Customized Results and Filter Bubbles

Search engines may customize their results based on a user's search history and preferences, which can create "filter bubbles" that limit exposure to diverse viewpoints and ideas.
