The bibliography
Numbers correspond to the small citation links in the biography. Source notes preserve firsthand attribution, edition differences and the limits of each record.
Edited studio coverage
Contemporary studio reporting; byline and full feature extent unverified.
1992 merger, founders and the studio at the date reported; not a personal staff credit on every title.
Edited participant account
Firsthand cofounder account gives April 1996; the June 1997 Red Herring profile gives February 1996. The year is supported; month unresolved. Early issue footers misprint 1998.
Art Min’s cofounder postmortem. Use his firsthand account, retain conflicting founding months and date the print issue to April 1999.
Subject self-publication
Self-reported career dates. Maxis entry has an incomplete end-date display.
Ordinary career facts about Lerner only, subject to authenticity and weight. Sims 2 details and 2025 independent work are self-reported.

Publisher’s retrospective statement; original page and report cover visually checked. Does not establish EA-wide revenue rank.
Attribute EA’s exact first number-one IBM PC bestseller statement. Does not establish revenue rank or an IPO connection.
Original manual verified
Original publisher manual visually verified on 2 November: Design: Ned Lerner. The credit applies to this Genesis edition.
Printed p. 43 explicitly credits Design: Ned Lerner. Other people have Programming and Technical Director credits. The website now cites this original directly.
Edited French interview
Two-page French interview inspected visually; next page is linked in the evidence catalog.
Two-page personal interview, pp. 86-87. Obtain accurate human translation for biography use; distinguish answers from editorial framing.

Edited participant interview

Green’s affiliation and graphics work. Useful institutional context; not proof of an absolute texture-mapping first.
Self-published third-party testimony

Diego identification is a research lead. Living-person policy prevents using this self-published third-party claim as the biography’s sole support.
Edited stream coverage
Corroborates the developer-stream context; does not independently repeat the likeness identification.
Confirms developer-playthrough context, but does not repeat the Diego/Lerner likeness identification. It cannot cure that sourcing gap.
Independent personal profile
Complete user-supplied excerpt visually read: cover plus five interior pages; no legible printed pagination. Gives February 1996 for Multitude, versus April in Min’s postmortem. Original scan and assessment are reproduced in the source packet.

The revised opening uses its bicycle business, Four-Phase retest and canceled-project anecdotes as period profile reporting. The 1985 EA agreement supports company activity, not legal incorporation or an IPO revenue claim.
Editorial selection
Original introduction and complete list read. Names Lerner and links his profile. Editorial selections are alphabetical, not ranked; this is Top 20, not top ten.
Top 20 Entrepreneurs of 1997 inclusion. The list is alphabetical, not a numerical rank or a Top 10 list.

PS3 Gran Turismo 6 tools-group Technology and Infrastructure credit; preserve hierarchy and platform.

Edited business reporting
Independent reporting; its Multitude founding year conflicts with contemporary/cofounder accounts.
Hearo’s 2020 open beta/funding. Its retrospective Multitude year conflicts with contemporary sources; use 1996 with conflict disclosed.
Independent retrospective with interviews
Full original read in Chrome3November2026. Locators: The early days; The founding fathers; From ashes. Retrospective interview evidence, not a named game credit. Later flight-sequel wording does not establish employment dates or personal credits on those releases.
Corroborates Lerner’s Underworld financing and simulation leadership; contextualizes studio influence. Interview recollections remain attributed. Not a named game credit or proof of personal responsibility for every studio innovation.
Published company biography
Company biography explicitly describes Lerner as a producer on John Madden Football ’93. The sentence does not identify the platform. The SEC hosts the filing; that does not make the biographical assertion independently verified.
Attribute the producer statement to the company biography. Genesis is Lerner’s own platform identification, separate from the published sentence and from the original game credit screens.
Period company-profile material
Original CD-ROM text files ARTICLES/PROFILE/NED.RTF and NL_BIO.RTF name Lerner as Chairman of the Board and Executive Vice President. FACTS.RTF lists the company’s games. The precise issue month and an individual article byline remain unverified.
Supports the published corporate titles and studio-level context. It does not create an individual System Shock or Ultima Underworld II producer, designer or programming credit.
Original publisher packaging
Original packaging scan visually read: front black margin says BY / NED LERNER / GENE KUSMIAK. A larger 3366×2100 copy is preserved by The Old Computer. The inspected back panel does not name either developer. This finding applies to the scanned U.S. layout, not every printing or region.
Supports prominent joint front-cover billing. The box byline does not allocate design versus programming; the original manual separately names Design: Ned Lerner and Programming: Gene Kusmiak. The archive is hosting the original artifact, not independently reporting its authorship.
Original publisher packaging
Both cover images visually read: BY / LOOKINGGLASS / TECHNOLOGY™ / AND / EA STUDIOS. The Video Game Company preserves an EASN-branded cover image; Trade-N-Games shows an actual EA Sports-branded box. Exact printing and photograph dates are not established.
Supports LookingGlass Technology and EA Studios being billed on Genesis packaging. It does not name Ned Lerner or independently prove his producer role. The shop pages locate the artifacts; their sales descriptions are not independent career reporting.

Channel: PlayStation Europe. PlayStation Europe’s full making-of documentary about the original game, offered as development context.
Original PlayStation Europe upload, not a dubbed reupload. This documentary covers the original PS3 game; it does not establish a new Lerner credit for that edition. Kept separately from the PS4 Remastered trailer.
