Apple's ascent to becoming the world's largest monopoly is attributed to its innovative products, strategic acquisitions, and ecosystem lock-in. Through groundbreaking devices like the iPhone and iPad, coupled with seamless integration across hardware, software, and services, Apple has cultivated a loyal customer base. Additionally, its App Store dominance and control over the iOS ecosystem further solidify its monopoly position. Critics argue that Apple's restrictive policies and practices stifle competition, leading to antitrust scrutiny. Despite this, Apple's market dominance remains largely unchallenged, making it a formidable force in the tech industry.
