All-in-one telephone

How this innovation came too late to the Netherlands.

Since the beginning of the 20th century, the telephone had consisted of two parts.  

There was the mechanism that made contact with the switchboard.  

And the receiver, which contained a microphone and a speaker.

Swedish telecom manufacturer Ericsson started working on a way to combine these separate sections in an all-in-one phone.  

This quest began in 1939, and around 1950 their brand-new model, the Ericofon, was born.

At that time, the Netherlands had only one telephone company: the PTT.  

And from 1965, the PTT supplied only one type of telephone: the T65.

Around 1979, it became possible for Dutch people to have a second phone in their homes. And that phone could also come from a different supplier.  

The PTT responded by offering its customers the Ericofon.  

It was promoted as the ideal second phone, perfect for your bedside table.  

The Ericofon was sold in three fashionable colours: warm red, bright white and dark brown.

Even so, there wasn’t much interest in the all-in-one phone. This was partly due to its outdated design.

By that time, Dutch consumers were used to pushing buttons, but the Ericophone still had a dial.

As a result, Ericsson’s innovative all-in-one phone has never been a success in the Netherlands.
