A talking book is a story you hear. 

A talking book is a recording of a story. 

An audiobook is a recording of a book. Someone reads the words out loud. You can listen to the whole book. This is called an unabridged version. If the recording is shorter, it is an abridgement. 
Thomas Edison helped start this idea. He invented the phonograph in 1877. He wanted it to speak to blind people. Early recordings were very short. They only lasted a few minutes. This made long books hard to hear. 
In the 1930s, new programs helped blind readers. They shared recordings between the US and Britain. Later, cassette tapes became popular in the 1970s. People could listen to them in cars. Small players like the Walkman made it easy to carry them. 
In 1997, a new way arrived. A company called Audible made a digital player. This let people download books from the internet. You did not need tapes or discs anymore. Now, you can listen to many books on small devices. 
An audiobook is a recording of a book being read out loud. You might hear the whole book from start to finish. This is called an unabridged version. Sometimes, a recording is a shorter version of the story. These are called abridgements. 
How do these recordings work? It all started with the phonograph. Thomas Edison invented this machine in 1877. He hoped it could speak to blind people. At first, recordings were on round cylinders. These cylinders only held about four minutes of sound. Later, flat discs could hold about 12 minutes. These were still too short for long books. By the 1930s, new records could hold 20 minutes. This made it easier to tell long stories. 
Many people helped grow the audiobook world. In 1931, the American Foundation for the Blind started a program. They wanted to help veterans and adults who could not see. They recorded things like the Bible and plays by Shakespeare. In 1952, two women named Barbara Holdridge and Marianne Roney started Caedmon Records. They were the first company to sell spoken recordings to the public. Their first release was poems by Dylan Thomas. This helped launch the whole industry in the United States. 
Technology changed how we listen to books. In the 1970s, cassette tapes became very popular. People could use small players like the Walkman to listen on the go. They could even listen in their cars. In 1984, a company called Brilliance Audio found a way to record more on one tape. They used both channels of a stereo track to fit twice as much sound. This made long, unabridged books much cheaper. By 1987, the audiobook market was worth $200 million. 
Today, the internet has changed everything again. In 1997, a company called Audible made a digital player. It was smaller and lighter than a Walkman. Digital books allow you to download stories instantly from the internet. You do not need to carry heavy tapes or discs anymore. You can carry many books on one small device. This connects to how we use computers and phones today. Audiobooks are now a huge part of how we enjoy stories. 
An audiobook is a recording of a book or other work being read out loud. These recordings come in two primary formats. An unabridged version is a reading of the complete, original text. An abridgement is a shorter version of the work. 
The mechanism of audiobooks began with the invention of the phonograph. Thomas Edison invented the phonograph in 1877. He envisioned "phonographic books" that could speak to blind people without effort. The first recorded verse was Edison's own recital of "Mary Had a Little Lamb." Early recording technology was very limited in capacity. In the late 19th century, recordings were made on cylinders. These cylinders could only hold about four minutes of sound. Later, flat platters increased storage to 12 minutes. However, these formats remained impractical for long books. By the 1930s, close-grooved records increased capacity to 20 minutes. This allowed for much longer narratives to be recorded. 
Different organizations and companies created distinct stages of audiobook development. In 1931, the American Foundation for the Blind and the Library of Congress started the "Talking Books Program." This program provided reading materials for veterans from World War I and other visually impaired adults. In 1948, Anne T. Macdonald founded Recording for the Blind & Dyslexic. She used six-inch vinyl SoundScriber phonograph discs to record textbooks. These discs played about 12 minutes of material per side. In 1952, Barbara Holdridge and Marianne Roney formed Caedmon Records. This was the first company dedicated to selling spoken word recordings to the public. Their first release featured poems by Dylan Thomas. 
Other pioneering companies helped expand the market to different audiences. Listening Library was founded in 1955 by Anthony Ditlow and his wife. They were among the first to distribute children's audiobooks to schools and hospitals. Spoken Arts was founded in 1956 by Arthur Luce Klein and his wife. They produced over 700 recordings, focusing on poetry and drama for schools. These companies benefited from the invention of the Long Play (LP) record in 1948. LPs made longer recordings more affordable and practical. However, LPs were still limited to about 45 minutes of total playing time. This meant most LPs featured short works like poems rather than full books.
The 1970s brought a major shift with the wide adoption of cassette tapes. Cassettes were invented in 1962, and the Library of Congress began distributing books on them by 1969. Several innovations helped the commercial market grow. Portable players like the Walkman became popular. Additionally, cassette decks became common in cars. In 1975, Duvall Hecht founded Books on Tape. This was a mail-order rental service for unabridged audiobooks. In 1978, Henry Trentman started Recorded Books. His company used professional actors and high-quality studio recordings. In 1984, Brilliance Audio invented a technique to record twice as much on one cassette. They did this by recording on each of the two channels of a stereo track. This made affordable, unabridged editions possible for a wider audience.
The audiobook industry reached a turning point in 1986. During this time, it matured from an experimental curiosity into a professional field. The Audio Publishers Association was established to promote awareness and provide industry statistics. Major clubs like the Book-of-the-Month club began offering audiobooks to members. By the end of 1987, the market was estimated to be worth $200 million. By the middle of the 1990s, the retail value grew to $1.5 billion per year. To honor excellence, the Audio Publishers Association established the Audie Awards in 1996. These awards are considered the equivalent of the Oscar for the audiobook industry.
Modern technology has further transformed how we access spoken word content. The spread of the internet and broadband in the 1990s increased popularity. In 1997, Audible pioneered the first mass-market digital media player. This device, called "The Audible Player," held two hours of audio. It was smaller and lighter than a Walkman. Digital audiobooks allow listeners to avoid physical media like cassettes or CDs. Instead, users can enjoy instant downloads from online libraries. This provides unlimited size and high portability.
