35 minutes after posting I thought I could make an improvement to my answer.

Electronic devices are a subset of electric devices. Electronic devices are characterized by being able to use an electric field or current (in a BJT) to control the flow of electrons through the device without using moving parts.

Apart from simple wire and transformers, in general Electric devices are electromechanical. They have moving parts.

Electronic devices have no moving parts. Early devices were tubes that operated through the use of electric fields. Later solid state devices were developed. Solid state devices are smaller and don’t require a “heater”. The point is these devices are called electronic because the movement of electrons is controlled with out using moving electric contacts.

Motors, generators, mechanical switches, lamps and electromechanical relays are all electric devices. The famous pioneer in the development of these devices was Tomas Edison.

Actually the telegraph was invented earlier and put to commercial use by Samuel F.B. Morse.

Initially electronic devices were in the form of vacuum tubes. These tubes started to become commercially available in the 1920's.

In 1947 the transistor (solid state electronic) was developed at Bell Labs.
