Alphabet is the parent of Google and was created through a corporate reorganization announced in August 2015.
Larry Page announced the restructuring in August 2015, and Alphabet became the publicly traded parent company later that year. Sundar Pichai became Google's chief executive, while Page became Alphabet's chief executive and Sergey Brin became its president.
The structure placed Google Search, YouTube, Android, and related products within Google, while other ventures could operate as separate Alphabet businesses. This arrangement was intended to give investors and managers clearer visibility into the company's different activities.
Alphabet's appearance among the world's largest companies is driven mainly by Google's advertising and cloud operations. The corporate name is distinct from Google's consumer brand, which is why market-cap tables may list Alphabet even though most people interact with Google products.
