Final answer:
Atari's first product released in 1975 was an arcade game called Pong. The success of Pong laid the groundwork for the video game industry and was followed by the release of the Atari Video Computer System in 1977, allowing for at-home gaming.
Step-by-step explanation:
The first product released by Atari in 1975 was an arcade game called Pong. It was a table tennis-themed game featuring simple two-dimensional graphics, and it is considered one of the earliest arcade video games. It was quite a success and played a major role in the establishment of the video game industry. However, the other options mentioned, like Space Invaders, Pac-Man, and Asteroids, were also popular games that were released afterwards and contributed to the golden age of arcade video games.
Later in 1977, the Atari Video Computer System was released, which could be connected to almost any television. This innovation allowed users to play video games at home. The system used small plastic cartridges that contained the software for the games, which were plugged directly into the machine to play different games. This development was crucial as it marked the transition from arcade to at-home gaming and led to the beginning of a new era for video games.
