The question asked: give me all search-engine companies that ever existed in history, thoroughly. This inventory is what a broad multilingual web scan (four passes, 7,611 URL-deduplicated result rows, as of 2026-08-29) could document: 1,090 engine–operator candidate records spanning pre-web retrieval systems of the 1960s through 2020s AI search — an extensive open-ended inventory, not a complete census. Blank cells mean unresolved, not "none".
Included: general web engines, web directories, portals, metasearch, privacy engines, regional and national engines, and public vertical engines (academic, shopping, travel, jobs, people, media, code, kids, dark-web and AI search). Excluded: internal enterprise-only search and site-search software. No public source can establish literally every search company ever created — many small, local, short-lived, pre-web and non-English projects left no trace. Operator ownership changed over time and automatic extraction can attach an owner mentioned on a page to the wrong service: treat single-source rows and surprising ownership as leads to verify via the linked source.
One bar per launch decade, split by consolidated category family; 134 raw source labels are folded into 12 families (raw labels appear on hover). The 1990s surge and the 525-record unknown-launch-year backlog dominate. Hover a segment for its exact count and source labels.
One row per extracted engine–operator pairing. Unresolved operators stay visible. Filter to the "General web" family if that is your definition of a search engine.
| Engine | Company / operator | Country | Launch | End | Status | Category (raw) | Src | Source |

One row per normalized company extracted by the scan. Counts are documented associations, not exact portfolios; rows flagged verify have surprisingly high counts where parent, acquirer and original operator may be conflated.
| Company | Services | Country | Launch span | Documented engine names | Source |

Method: automated multilingual web scan finished 2026-08-29; four broad search passes over 7,611 URL-deduplicated result rows with overlap between passes. Service table: 1,090 extracted engine–operator records (648 distinct engine names); company index: 344 normalized operators; chart: launch-decade × category counts with 134 raw category labels consolidated into 12 families for display. "Ended" counts services with an extracted end date or defunct status (147). Blank cells mean the value was unresolved in scanned sources, not absent in reality. Internal enterprise and site-search products were excluded; small, pre-web, non-English and undocumented projects are underrepresented. This is an open-ended inventory, not a universal census.
