New Delhi, Sep 05 (ANI): E-commerce company Amazon on Tuesday became the second American company to cross USD 1 trillion in value. The Jeff Bezos-founded company and Apple now make up more than eight percent of the entire value of the S-P 500, CNN quoted senior index analyst for S-P, Howard Silverblatt as saying. The company's stock reportedly rose nearly two percent in the morning trading, thereby putting its market value just over the 13-digit territory. Amazon, in just two decades, expanded far beyond its bookseller beginnings. It has revolutionised how people shop online. Apple topped the USD 1 trillion mark in early August.
