Overview
Emile Berliner (1851–1929) patented the gramophone in 1887, using a flat disc with a lateral-cut groove instead of Edison's vertical-cut cylinder. The disc could be electroplated into a metal master and stamped in quantity, which turned recorded sound from a curiosity into a manufacturing industry. He had earlier developed a carbon microphone transmitter.

Steps
The problem as it stood
Cylinders could not be duplicated efficiently. Early recording sessions ran multiple machines simultaneously and performers repeated a piece dozens of times to build stock. No mass market is possible on that basis.
What he actually did
Berliner moved to a flat disc and to lateral modulation, then developed a process for electroplating a recording into a durable metal negative from which copies could be pressed. The Victor Talking Machine Company and its European affiliates were built on it.
How it worked
A flat surface can be pressed against a stamper under heat; a cylinder cannot, without sophisticated moulding. Lateral modulation keeps groove depth constant, which makes the stamping geometry straightforward. Discs also store flat, ship cheaply and survive handling — a set of unglamorous advantages that together settled the format.
What it made possible
The record industry: mass duplication, catalogues, hit records, and a physical object cheap enough for a household. The disc remained the dominant format for a century, and the lateral groove survived into the stereo LP with Blumlein's 45/45 scheme.
What happened to him
Berliner also worked on acoustics and aviation. His carbon transmitter work fed into the telephone, and the Berliner name is attached to the Gramophone Company and its "His Master's Voice" trademark. He died in 1929.
Where the credit landed
Berliner is properly credited for the disc, though the framing usually emphasises sound quality when the decisive advantage was manufacturing. His carbon microphone work is more contested and sits inside the tangle of telephone-transmitter patents involving Bell, Edison and Hughes. The disc is the unambiguous contribution and the more consequential one.
Pro Tips
- Discs won on duplication economics, not on sound quality.
- Lateral cutting keeps groove depth constant, which is what makes stamping practical.
- Early cylinder sessions meant performing the same piece dozens of times.

What You'll Learn
Format wars are usually decided by manufacturing, not by fidelity.
From one master to a million copies
Berliner's process recorded into a soft surface, electroplated that to make a metal negative, and used the negative as a stamper to press copies in shellac. The economics are those of printing: high setup cost, near-zero marginal cost. That is what a mass medium requires, and it is why the disc displaced a format its inventor considered sonically superior.
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: Why did records beat cylinders?
A: Because a flat disc can be stamped from a metal master in quantity while a cylinder cannot be duplicated efficiently. Discs also stored and shipped better. The decisive advantage was manufacturing economics rather than sound quality.
Q: What is lateral-cut recording?
A: The groove wanders from side to side at constant depth, rather than varying in depth as in Edison's vertical-cut cylinders. Constant depth makes stamping duplicates straightforward.
