All Diversified Telecommunication Services Companies in the United States

This second-level group collects the United States members of the Diversified Telecommunication Services group: American incumbent, alternative and internet service provider companies, from historic Bell System descendants such as Verizon and AT&T through cable-broadband and fiber entrants to small regional dial-up pioneers now defunct. It exists purely to keep the parent Diversified Telecommunication Services group's member count workable once split by region alongside its Europe, Asia-Pacific and Rest of the World siblings.
