150,000 units were sold that holiday season. The game became Sears' most successful product at the time, which earned Atari a Sears Quality Excellence Award. Atari's own version sold an additional 50,000 units. Similar to the arcade version, several companies released clones to capitalize on the home console's success, many of which continued to produce new consoles and video games. Magnavox re-released their Odyssey system with simplified hardware and new features and, later, released updated versions. Coleco entered the video game market with their Telstar console; it features three Pong variants and was also succeeded by newer models.

Bill Loguidice and Matt Barton of Gamasutra referred to the game's release as the start of a new entertainment medium, and commented that its simple, intuitive gameplay made it a success. In 1995, Flux magazine ranked the game 56th on their "Top 100 Video Games." In 1996 Next Generation named it one of the "Top 100 Games of All Time", recounting that "Next Generation staff ignor[ed] hundreds of thousands of dollars of 32-bit software to play Pong for hours when the Genesis version was released." In 1999, Next Generation listed Pong as number 34 on their "Top 50 Games of All Time", commenting that, "Despite, or perhaps because of, its simplicity, Pong is the ultimate two-player challenge – a test of
