RIO vs CMCSA Comparison

Rio Tinto is a global diversified miner. Iron ore is the dominant commodity, with significantly lesser contributions from copper, aluminum, diamonds, gold, and industrial minerals. The 1995 merger of RTZ and CRA, via a dual-listed structure, created the present-day company. The two operate as a single business entity, with shareholders in each company having equivalent economic and voting rights. Major assets included the Pilbara iron ore operations, a 30% stake in the Escondida copper mine, 66%-ownership of the Oyu Tolgoi copper mine in Mongolia, the Weipa and Gove bauxite mines in Australia, and six hydro-powered aluminum smelters in Canada.

Comcast is made up of three parts. The core cable business owns networks capable of providing television, internet access, and phone services to 65 million US homes and businesses, or nearly half of the country. The firm provides services to about half of the locations in this territory. Comcast acquired NBCUniversal from General Electric in 2011. NBCU owns several cable networks, including CNBC, MSNBC, and USA, the NBC network, the Peacock streaming platform, several local NBC affiliates, Universal Studios, and several theme parks. The firm plans to spin off most of its cable networks. Finally, Sky, acquired in 2018, is a large television provider in the UK and Italy.
