<human>:  Can you give me a brief overview of the history of video games?
<bot>: Video games have been around for decades, dating back to the early 1970s. Early arcade games such as Pong and Space Invaders were some of the earliest and most popular video games. With the introduction of the home console and personal computer in the late 1970s and 80s, video games began to become more available to the public. Console gaming became more popular with the introduction of the Nintendo Entertainment System in 1985 and the introduction of the Sony Playstation in 1994. Since then, video game technology has advanced exponentially, leading to the introduction of 3D graphics, the development of the first-person shooter genre, and the introduction of mobile gaming with smartphones. In recent years, gaming has become more of an online, social experience with the introduction of massively multiplayer online games, which allow players to connect and play with each other online.
