They Pressed Play on an Old Answering Machine. They Weren’t Prepared for What They Heard.

It looked like nothing special.

An old beige answering machine sat on a table at an estate sale with a $5 price tag. Most people walked right past it.

One person took it home.

Inside was a tiny microcassette. They plugged the machine in, pressed Play and heard a man’s voice.

“Hi, it’s Dad. We’ll see you Sunday.”

The messages that followed weren’t mysterious or dramatic. They were ordinary conversations about birthdays, dinner plans and grocery lists.

But that’s what made them unforgettable.

The people leaving those messages had no idea a stranger would hear their voices decades later. For some families, those forgotten recordings may be the last time a loved one’s voice was ever captured.

It raises a fascinating question: How many answering machines are still sitting in attics, closets and thrift stores with hidden time capsules waiting to be discovered?

This week on the podcast, we look back at the answering machine, the device that quietly recorded everyday life and, in some cases, preserved memories no one knew they would one day treasure.

Answering machines evolved over more than a century as technology for recording and replaying sound improved.

Late 1800s: The idea became possible after Thomas Edison invented the phonograph in 1877, which could record and play back sound. Early recording devices were too expensive and impractical for everyday telephone use.
Early to mid-1900s: As telephones became common, inventors experimented with devices that could automatically answer calls and record messages. Most early systems were used by businesses rather than households.
1949: One of the first commercially successful answering devices, the Electronic Secretary, was introduced in the United States. It used wire recording technology and was large and expensive.
1960s: Compact magnetic tape technology made answering machines smaller, more reliable, and more affordable. Reel-to-reel tape systems gradually gave way to cassette-based machines.
1970s–1980s: Answering machines became a common household appliance. Features such as remote message retrieval, outgoing message recording, call screening, and message counters became standard. Prices fell enough for widespread consumer adoption.
1990s: Digital answering machines replaced tape in many homes. They stored messages in electronic memory, eliminating tapes and allowing quicker access to recordings.
2000s to today: Standalone answering machines declined as voicemail services provided by telephone companies and mobile carriers became standard. Smartphones and internet-based communication further reduced their use, though voicemail remains the direct descendant of the traditional answering machine.
