Overview
Peter Carl Goldmark (1906–1977) directed CBS Laboratories through the development of the microgroove 33⅓ rpm long-playing record, introduced in 1948, and also developed CBS's field-sequential colour television system. His credit for the LP is contested from an unusual direction: CBS's own president, William Paley, wrote that Goldmark did not do the work himself.

Steps
The problem as it stood
A 78 rpm disc held about four minutes a side, so any substantial work meant a stack of discs and interruptions every few minutes. Longer playing needed a finer groove, slower rotation, and a lighter pickup that would not destroy either.
What he actually did
Goldmark led the CBS Laboratories programme that combined 33⅓ rpm rotation, a microgroove roughly a third the width of the 78 groove, vinyl instead of shellac, variable groove pitch, and a lightweight pickup — producing over twenty minutes a side.
How it worked
The pieces interlock. Finer grooves need a smaller stylus and lower tracking force or they wear instantly; vinyl is quieter and tougher than shellac; variable pitch packs grooves closer during quiet passages. William Bachman engineered the heated stylus and variable-pitch cutting, and René Snepvangers the lightweight pickup.
What it made possible
The album as a form. Classical works on one side, and eventually the popular album as a coherent artistic unit rather than a bundle of singles. The LP dominated recorded music for forty years.
What happened to him
His field-sequential colour television system was briefly adopted by the FCC in 1950 and then displaced by RCA's compatible system, because it could not be received on existing monochrome sets. He later worked on EVR video recording and rural communications.
Where the credit landed
The microgroove LP was developed at CBS Laboratories under Goldmark's direction, with essential engineering by William Bachman and René Snepvangers. CBS president William Paley wrote that Goldmark "didn't actually do any of the work" on it — an unusually direct contradiction from inside the same organisation. Goldmark led the programme; the characterisation of his personal technical contribution is disputed by his own employer.
Pro Tips
- The LP is several interlocking innovations, not one — groove, speed, material, pitch, pickup.
- CBS's own president disputed Goldmark's personal contribution in print.
- His colour TV system lost because it was incompatible with existing sets.

What You'll Learn
A rare case where the internal contradiction is documented rather than inferred.
Why compatibility beat quality, again
Goldmark's field-sequential colour system produced good pictures and could not be received on the monochrome sets already in homes. RCA's system was technically more compromised and fully compatible, and it won — the same dynamic that later shaped PAL and SECAM. Compatibility with installed equipment is one of the most reliable predictors of which standard survives, and it beats picture quality nearly every time.
Where This Fits
This guide covers one specific part of the history of media technology. The wider picture — how each link in the chain from capture through transmission to display was actually built, who built it, and why the credit so often landed somewhere else — is in A History of Broadcast Technology: The Chain From Capture to Screen, which frames the discipline as a whole and links out to the detailed guides underneath it, including this one.

FAQ
Q: Who invented the LP record?
A: It was developed at CBS Laboratories under Peter Goldmark's direction, with essential engineering contributions from William Bachman and René Snepvangers. CBS president William Paley later wrote that Goldmark did not do the work himself, which makes his personal contribution genuinely disputed.
Q: Why did CBS colour television fail?
A: Its field-sequential system was incompatible with existing monochrome receivers, so those sets could not display its broadcasts at all. RCA's compatible system was adopted instead.
