A man realized he needed to purchase a hearing aid, but didn't want to spend a lot of money. "How much do they cost?" he asked the salesman.
"Anything from $2 to $2,000."
"Can I see the $2 model?" said the customer.
The salesman put the device around the man's neck, and said: "You just stick this button in your ear and run this little string down into your pocket."
"How does it work?" asked the customer.
"For $2, it doesn't work," said the salesman. "But when people see it on you, they'll talk louder."

First electron tube

In 1904, the first electron tube, a diode thermionic valve, was invented by John Ambrose Fleming. The valve consists of a carbon or tungsten filament lamp, to which is added a metal plate (insulated from the filament), and a connecting wire brought through the glass wall of the bulb to a third terminal outside. When battery current is applied to the filament making it incandescent, the space between the filament and the insulated plate will be found to conduct elecrons in only one direction. That means if the valve is connected in a circuit in with an oscillating current, its one-way conductivity will convert the oscillating current into a unidirectional current capable of actuating a telephone receiver. He notified Marconi in a 30 Nov 1904 letter.
