MTV-1

It was shown to the public at trade shows in London and Chicago in January, 1977, and released for sale in 1978.

The MTV-1 used an AEG Telefunken 2-inch (5.1 cm) black-and-white, electrostatic deflection cathode ray tube (CRT) and included a rechargeable 4-AA-cell NiCad battery pack.

It was able to receive either PAL or NTSC transmissions on VHF or UHF, the world's first multi-standard TV.

Custom ICs made by Texas Instruments and Sinclair contributed to its small size and low power consumption.

The original US$395 (about £205[1]) price tag proved to be too high to sell many of them, and Sinclair lost over £1.8 million in 1978, eventually selling its remaining inventory to liquidators at greatly reduced prices.
