Source-derived summary

CMC Limited was an information technology services, consulting and software company owned by Government of India headquartered in New Delhi, India . In 2001, CMC was sold by Government of India to Tata Consultancy Services and its owner, the Tata Group by the Indian Government.

History

CMC was incorporated on 26 December 1975, as the 'Computer Maintenance Corporation Private Limited'. The Government of India (GoI) held 100 percent of the equity share capital. On 19 August 1977, it was converted into a public limited company, again wholly owned by the GoI.

In October 2001, CMC was privatized by the GoI, and was divested to a leading Indian IT firm, Tata Consultancy Services (TCS), which is the largest software services company in Asia.

In 1977, the Janata Party government took office in India. US-based MNCs which were operating in India were told to shut shop and ship out. IBM was one of the companies told to leave. In 1978, CMC took over the maintenance of IBM installations at over 800 locations around India. Subsequently, it also took over the maintenance of computers supplied by other (non-IBM) foreign players.

Editorial summary

This brief starts where responsible research should: with the source description of “CMC Limited” as indian technology services company. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—2001, 1975, 1977, 1978—that can be checked directly. The linked authority record independently contributes the date 1975-12-26. The account is most persuasive where Limited, Indian and technology can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as indian technology services company. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 2, 2026. The linked authority identifier is Q5012868. VIAF identifies the subject as 126732633. The Library of Congress control number is n85106945. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2001, 1975, 1977 and 1978.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
