O’Reilly Media is an independent technology learning and publishing company whose roots date to 1978, with Tim O’Reilly as founder and chief executive. The company’s own history describes its beginnings as a technical-writing consulting firm and says it started publishing books about programming and computer technology in 1984. That distinction is useful because O’Reilly today is much more than a book publisher. Its current business centers on the O’Reilly learning platform, which combines books and other text with live training, interactive learning, video, certification-oriented material and other resources for individuals and organizations.
The exact catalog, training schedule and certification partners change continuously, so those counts and names should not be fixed into Profile details. O’Reilly’s history also includes businesses and programs that no longer operate in the same form. Safari Books Online began as a joint venture with Pearson in 2001; O’Reilly acquired Pearson’s interest in 2014 and ultimately integrated the service into O’Reilly online learning. The company also organized major technology conferences for many years but closed the main conference portion of the business in 2020.
A current profile should therefore avoid presenting historical conferences or Safari as separate current flagship businesses. O’Reilly Media, Inc. is a Delaware corporation, and first-party corporate history identifies Sebastopol, California as its headquarters, with additional offices historically listed in Boston, the United Kingdom, Tokyo and Beijing. The company’s support model is clear and region-specific. The official Support Center provides a contact form plus telephone support for the Americas at 1-800-889-8969, Europe at +44 20 3355 9998 and Asia Pacific at +61 29 191 9777, with operating hours published on that page.
Those numbers belong to O’Reilly learning support; they should not be mixed with unrelated book-distribution contacts or old conference contacts found in archived pages. Tim O’Reilly’s current official biography continues to identify him as founder and CEO, while the company About page describes a mission of sharing the knowledge of innovators and says the business has operated for more than 45 years. For users, the practical distinction is between the subscription learning platform, organization or institutional access, and separately purchased books or products; billing, access and support may differ by channel.
identity, Sebastopol headquarters, technology and business learning focus and oreilly.com official domain. Course counts, subscriber totals, current live events and temporary offers should be treated as changing service information rather than evergreen company facts. O’Reilly’s publishing heritage can also create confusion in support directories because print and ebook distribution, individual learning subscriptions and enterprise learning accounts are not necessarily handled in the same way. A reader who bought a book through a retailer should first consider the seller and edition involved, while a user who cannot sign in to the learning platform should use the online-learning Support Center.
Organization users may access O’Reilly through an employer, university, library or other institution, which can affect authentication and subscription administration. The company’s current support page specifically asks users to provide details about how they access the service when contacting support, reflecting that difference. O’Reilly should also not be confused with O’Reilly Auto Parts, an unrelated retailer with a similar name. The technology company’s official domain is oreilly.com, its visual identity uses the O’Reilly name in the technology-learning context, and its verified LinkedIn company page identifies Sebastopol as headquarters and 1978 as the founding year.
The firm remains privately held. Although O’Reilly has long played a prominent role in technology publishing and industry terminology, historical achievements are background rather than a substitute for describing the current learning service. A useful profile therefore explains both the company’s publishing roots and the present subscription platform, while sending account and access problems to the current Support Center instead of relying on archived contact pages.
