Which video game system was the first one ever made and who made it

In 1972 that Magnavox released the first home video game console which could be connected to a TV set---the Magnavox Odyssey, invented by Ralph H. Baer. The Odyssey was initially only moderately successful, and it was not until Atari's arcade game Pong popularized video games, that the public began to take more notice of the emerging industry. By the autumn of 1975 Magnavox, bowing to the popularity of Pong, cancelled the Odyssey and released a scaled down console that only played Pong and hockey, the Odyssey 100.
