Did You Know When the Answering Machine Was Invented?

When Was the Answering Machine Invented?

The answering machine is an electronic device that allows people to leave voice messages when they are unable to answer a phone call. It has become an essential tool in modern communication, but when was it invented? Let's find out.

The First Recording Devices

Before the actual answering machine, various recording devices were invented such as the phonograph and the wire recorder. These machines could record and play back sound but were not designed specifically for answering phones.

In the early 1900s, telephone companies started experimenting with ways to record messages when their operators were unavailable. In 1917, the first practical phone answering machine was patented by a Danish inventor called Valdemar Poulsen. His invention was called the "Telegraphone" and could record and play back phone messages.

However, the Telegraphone was not widely available and was used mostly by businesses and government agencies. It was not until the 1930s that the first automatic answering machine was invented.

The First Automatic Answering Machine

The first automatic answering machine was invented in 1935 by Willy Muller, a German inventor. His device was called the "Kurznotiz" and was designed to automatically answer phone calls and record messages on a magnetic wire. The Kurznotiz was a significant breakthrough in communication technology and paved the way for modern answering machines.

However, the Kurznotiz was not commercially successful and was mostly used by government agencies and large businesses. It was not until the 1950s that the answering machine became widely available to the general public.

Commercial Introduction of the Answering Machine

The first commercially successful answering machine was introduced in the US in the early 1950s. The machine was called the "Electronic Secretary" and was made by the American company Bell Labs. It used magnetic tape to record and play back messages.

At first, the Electronic Secretary was expensive and only affordable for businesses. However, as the technology improved and competition increased, the prices came down, and answering machines became affordable for the general public. By the 1970s, answering machines had become a common household item and were an essential part of modern communication.

In conclusion, the answering machine has come a long way from the early recording devices to the automatic answering machines of today. While technology has improved, the basic function of the answering machine remains the same – providing people with a way to leave messages when they cannot answer the phone.

How Did the Answering Machine Evolve?

The Magnetic Tape Era

During the 1960s, answering machines underwent a significant change with the introduction of magnetic tape technology. Prior to this, answering machines recorded messages on wire recorders, which had limited recording time and poor sound quality. However, magnetic tape technology vastly improved this by providing longer recording time and better sound quality.

The evolution of answering machines during this era also saw the introduction of various features such as the ability to rewind and fast forward messages, and the option to easily erase specific messages without having to erase the entire tape. This improved functionality and capability made answering machines more user-friendly and reliable.

The Digital Era

The 1980s ushered in a new era for answering machines with the emergence of digital technology. Digital answering machines introduced even longer recording time and superior sound quality, which meant that users could store more messages without losing any of the sound quality.

Digital answering machines also offered additional features such as message retrieval from remote locations, allowing users to access their messages from any phone, irrespective of location. This was a significant improvement from the previous era, where users needed to be in the same location as their answering machine to listen to their messages.

The Integration with Caller ID Technology

By the mid-1990s, the evolution of answering machines saw another major improvement with the integration of caller ID technology. This technology enabled users to identify and screen incoming calls before answering, giving them the option to either take the call or let it go to voicemail.

The integration of caller ID technology also solved the problem of not being able to know who had called or left a message when the user was not at home. This feature gave users the ability to know who had called and to return the call if necessary.

Since then, answering machines have continuously evolved with features such as message notifications, call screening, and even full integration with mobile devices and voice assistants.


In conclusion, answering machines have come a long way since their invention in the 1930s, with each era of technological advancement introducing new features that have revolutionized the way we communicate. From the magnetic tape era to the digital era, and finally the integration of caller ID technology, answering machines have become more than just devices that record messages. They are now comprehensive communication tools that provide convenience and reliability to their users.

Are Answering Machines Still Used Today?

The Decrease in Popularity

With the growth of mobile phones and voicemail services, the use of answering machines significantly decreased since the early 2000s. People find it more convenient to have their calls directly forwarded to their mobile phones instead of going through a separate machine. In addition, the rise of smartphones came with new features such as visual voicemail, which provides a visual interface for managing voicemail messages, making it easier for people to access and manage their messages.

Furthermore, voicemail services provided by cellular network providers are now integrated into mobile phones, making it even easier for people to access their messages. The decline in the use of answering machines is not just limited to individuals, but also businesses who prefer to have a professional and more immediate way of answering calls.

The Continued Use in Business

Answering machines are still used by businesses for various reasons such as providing customer support and after-hours messaging. Although a lot of companies have moved to automated phone systems, some businesses still use answering machines to provide a more personal touch to customer service. The messages left on answering machines are also more comprehensive, which allows businesses to prioritize and easily manage messages left by customers. This ensures that all calls are answered and important messages are not missed.

In addition, answering machines provide a cost-effective way for small businesses to manage their calls outside business hours. Some companies prefer not to outsource their customer support, and having an answering machine in place ensures that customers' messages are recorded for later retrieval. This way, businesses can provide their customers with an assurance that their calls are being taken seriously and will be addressed soon.

The Nostalgia Factor

Despite the decrease in popularity, some individuals still use answering machines for nostalgic purposes or as a backup to their mobile phones. For instance, some people enjoy leaving personalized messages on answering machines, while others keep them as a memory of the past. Answering machines have been replaced with high-tech gadgets, but some individuals still keep these machines in their homes as a memento of previous times. Others use answering machines as a backup to their mobile phones, as they are still reliable when it comes to recording important calls or messages.

In conclusion, answering machines are not as popular as they once were, but they still have their uses. Their decline in popularity can be attributed to the widespread use of mobile phones and voicemail services. However, they are still a valuable tool for businesses that want to provide their customers with a more personalized service. Additionally, some individuals still enjoy using them out of nostalgia. With the recent rise in vintage technology, answering machines may continue to be used for their unique qualities and charm.
