Simon is an electronic game of memory skill invented by Ralph H. Baer and Howard J. Morrison, with software programming by Lenny Cope, The original version was manufactured and distributed by Milton Bradley but now the game is currently manufactured by Hasbro with their latest game called Simon Swipe which was demonstrated at the New York Toy Fair in February 2014 and released in Summer 2014 as planned. Much of the assembly language was written by Dr. Charles Kapps, who taught computer science at Temple University and also wrote one of the first books on the theory of computer programming. Simon was launched in 1978 at Studio 54 in New York City and was an immediate success, becoming a pop culture symbol of the 1970s and 1980s.
Ralph H. Baer and Howard J. Morrison  were first introduced to Atari’s game Touch Me at the Music Operators of America (MOA) trade show in 1976. Baer said of the product, “Nice gameplay. Terrible execution. Visually boring. Miserable, rasping sounds.” The original prototype, built by Baer, included the Texas Instruments TMS 1000 microprocessor chip, which was low cost and used by many games of the 1970s. Lenny Cope, who was one of Ralph H. Baer’s partners, worked on the programming code for the core of the game, titled Follow Me at the time. Baer developed the tones of the game, inspired by the notes of a bugle. It was when they pitched the demo, an 8-inch-by-8-inch console, to the Milton Bradley Company that the name of the game was changed to Simon. Simon debuted in 1978 at the cost of $24.95 (equivalent to $90 in 2015) and became one of the top selling toys that Christmas.
Since 2013, KID Group now owns the rights to Simon and Hasbro manufacture Simon games. Dan Klistner, the inventor of Bop It, released Simon Swipe in 2014 which has touch screen input and four games which are called Levels, Classic Simon, Multiplayer and Extreme Simon. 
The device has four colored buttons, each producing a particular tone when it is pressed or activated by the device. A round in the game consists of the device lighting up one or more buttons in a random order, after which the player must reproduce that order by pressing the buttons. As the game progresses, the number of buttons to be pressed increases. The US patent for this game, Pat No. 4,207,087 was obtained in 1980 by patent counsel for Marvin Glass and Associates, Robert J. Schneider, a managing partner with the firm of Mason, Kolehmainen, Rathburn and Wyss. Mr. Schneider’s partner at the firm, noted electrical engineer and patent attorney, Stanley Tomsa drafted and prosecuted the patent application which resulted as Pat No. 4,207,087. Mr. Schneider also procured US Design Pat. No 253,786 for the game housing which was invented by Douglas Montague, a designer at Marvin Glass and Associates. Mr. Schneider is currently Co-Chair of the Intellectual Property Department of Taft, Stettinius & Hollister LLP. Stanley Tomsa’s son Michael Tomsa is currently a patent attorney at Katten Muchin Rosenman LLP
Simon is named for the simple children's game of Simon Says, but the gameplay is based on Atari's unpopular Touch Me arcade game from 1974. Simon differs from Touch Me in that the Touch Me buttons were all the same color (black) and the sounds it produced were harsh and grating.
Simon's tones, on the other hand, were designed to always be harmonic, no matter what order they were played in, and consisted of an A major triad in second inversion which resembles a Trumpet fanfare:
- E-note (blue, lower right);
- C♯-note (yellow, lower left);
- A-note (red, upper right).
- E-note (green, upper left, an octave lower than blue);
Simon was later re-released by Milton Bradley – now owned by Hasbro – in its original circular form, though with a translucent case rather than plain black. It was also sold as a two-sided Simon Squared version, with the reverse side having eight buttons for head-to-head play, and as a keychain (officially licensed by Fun4All) with simplified gameplay (only having Game 1, Difficulty 4 available). Other variations of the original game, no longer produced, include Pocket Simon and the eight-button Super Simon, both from 1980. Finally, Nelsonic released an official wristwatch version of Simon.
Later versions of the game being sold include a pocket version of the original game in a smaller, yellow, oval-shaped case; Simon Trickster, which plays the original game as well as variations where the colors shift around from button to button (Simon Bounce), where the buttons have no colors at all (Simon Surprise), or where the player must repeat the sequence backwards (Simon Rewind); and a pocket version of Simon Trickster.
In the latest version, Simon Swipe, the notes are as follows:
- G-note (blue, lower right);
- C-note (yellow, lower left);
- E-note (red, upper right).
- G-note (green, upper left, an octave higher than blue)
The swiping sounds are presented with a pitch bend.
As a popular game, Simon inspired many imitators and knockoffs. Most notably, Atari released a handheld version of Touch Me in 1978, with multicolored buttons and pleasant musical tones. Despite being named for their older arcade game, the handheld Touch Me contained Simon's three game variations and four difficulty levels, albeit with limits of eight, 16, 32, and 99 instead of eight, 14, 20 and 31. Even its button layout mirrored Simon's, with blue in the upper-left, yellow in the upper-right, red in the lower-left, and green in the lower-right, the same layout as Simon turned upside-down. Its only unique features were a LED score display, similar to the one its arcade counterpart had, and its small size, similar to a pocket calculator.
Other clones include:
- A Simon clone called Monkey See, Monkey Do which featured a similar casing as that of Simon, except that the buttons were oval-shaped.
- Tiger Electronics' Copy Cat in 1979, re-released with a transparent case in 1988 and used buzzers.

The same gameplay also appears on multi-game handhelds such as:

- Atari also included a nine-button version of Touch Me as game variations 1-4 (out of 19) on the 1978 Brain Games cartridge for the Atari 2600.

- A Harry Potter wand released in 2001 called 'Harry Potter Magic Spell Challenge' also made by Hasbro had Simon gameplay and voice commands which are 'Wingardium' and 'Leviosa'.
Some versions of the game have tones that play as long as you push the button down. Others have a constant time of the sound. Other versions feature audio themes: animals (cat/dog/pig/cow), xylophone, football, galaxy (space sounds), some of which (animals, football) make the game easier to play. Yet others can have sound on/off setting, making the game harder by relying just on visual cues.
