When were video games first made

William Higinbotham's "Tennis for two" was not TECHNICALLY a video game. This is proven by the fact that Nintendo tried to sue Ralph Baer (the creator of the first true console, the "Magnavox Odyssey") and invalidate Ralph's patents with the above statement that "Tennis for two" was the first. The court ruled in favor of Baer, because "Tennis for two" lacked the use of video signals.
