Amazon.com, Inc. founded in 1994 by Jeff Bezos in the cozy confines of his Seattle garage, Amazon.com, Inc. quickly evolved from a humble online bookstore to a colossal e-commerce powerhouse. Today, it offers an extensive range of products from DVDs and electronics to furniture and groceries. With a global footprint that spans continents—from Canada and the UK to Japan and Brazil—Amazon's presence is truly international. The company has not only diversified into various domains, including acquiring Twitch in 2014 and venturing into the film industry in 2015, but also introduced initiatives like the brand registry program to safeguard intellectual property. Despite the hurdles of labor relations and competitive practices, Amazon remains a dominant force in the global e-commerce landscape.
