It holds the distinction of being the highest-selling single computer model globally to date.
The Commodore 64 (C64), launched in 1982, achieved unprecedented commercial success primarily due to its competitive pricing, advanced sound capabilities (through its SID chip), and impressive graphics for its era. These features made it a highly attractive option for gaming and general home use. As a result, it sold millions of units worldwide and, according to Guinness World Records, remains the best-selling single computer model of all time. Option A is incorrect; the C64 was an 8-bit machine. 16-bit home computers like the Apple IIGS and Amiga 1000 came later. Option C is incorrect; hard drives were expensive and rare in early home computers, typically offered as external peripherals if at all. Option D is incorrect; while the C64 had a graphical display, it primarily used a command-line interface. The Apple Macintosh, introduced in 1984, was the major pioneer in popularizing the graphical user interface for mass markets.
