IRIG standard 212-00 defines a different time-code, based on RS-232-style asynchronous serial communication. The timecode consists of ASCII characters, each transmitted as 10 bits: 1 start bit; 7 data bits; 1 odd parity bit; 1 stop bit; The on-time marker is the leading edge of the first start bit.
IRIG-B timecode consists of 100 bits, repeated each second. Every tenth bit is a "position identifier", and most of the remainder encode the current time (date, hour, minute and second). Bits 60–68 and 70–78 are reserved for other uses; IEEE 1344 is such a use. It defines the bits as follows:
The Inter-Range Instrumentation Group (IRIG) is the standards body of the Range Commanders Council (RCC). The group publishes standards through the RCC Secretariat at White Sands Missile Range . The best known IRIG standard is the IRIG timecode used to timestamp video, film, telemetry, radar, and other data collected at test ranges.

I would suggest starting the article with a brief description of what IRIG time codes are, i.e. a dummed down description of what they are and what are they used for and stuff, before writing the history of them. Most people, including myself, search terms in wikipedia to get a quick idea of what those sort of technical terms mean.
IRIG may mean: The Inter-Range Instrumentation Group, a standards publishing body Inter-range instrumentation group time codes, the best known IRIG standards;
A timecode (alternatively, time code) is a sequence of numeric codes generated at regular intervals by a timing synchronization system. Timecode is used in video production , show control and other applications which require temporal coordination or logging of recording or actions.
