Since that effort to discredit Apple became part of society’s thoughts about the Mac vs PC debate, you can still hear people using the advertising pitch as their justification to buy what is ultimately a more expensive system. When people use macOS, they often feel that the system is better. IBM asked them to provide DOS to the personal computer, eventually resulting in a $1 billion campaign against Apple products.Īlthough IBM’s efforts failed for itself, Microsoft benefitted from the marketing campaigns. At the time, the only item in their portfolio was called Microsoft Basic, and even it had been allegedly copied from another company. When the computer developer needed a product to compete with the Apple I and Apple II, IBM contacted Microsoft. Why does Windows have such a dominant percentage of the computing marketplace? This comparison requires us to look at Microsoft’s history with IBM briefly. MacOS currently holds a 17% part of the market, while Linux and ChromeOS clean up the remaining percentages. About 3 out of every 4 computers (77.74%) that people are using globally right now use the Microsoft platform. Windows holds a significant market share compared to Mac systems.
