Alphabet Inc. is an American multinational technology conglomerate holding company headquartered in Mountain View, California. Alphabet is the world's third-largest technology company by revenue, after Amazon and Apple, the largest technology company by profit, and one of the world's most valuable companies. It was created through a restructuring of Google on October 2, 2015, and became the parent holding company of Google and several former Google subsidiaries. Alphabet is listed on the large-cap section of the Nasdaq under the ticker symbols GOOGL and GOOG; both classes of stock are components of major stock market indices such as the S&P 500 and NASDAQ-100. The company is considered one of the Big Five American information technology companies, alongside Amazon, Apple, Meta, and Microsoft. The establishment of Alphabet Inc. was prompted by a desire to make the core Google business "cleaner and more accountable" while allowing greater autonomy to group companies that operate in businesses other than Internet services.
