Cable Leads U.S. ISP Accounts, Telcos have Most to Gain

AT&T, Comcast and Charter Communications own networks covering the most U.S. residents (and presumably housing units). But it is difficult to directly correlate population covered with “homes passed” or even “locations served.” 

Most locations are served by at least two different terrestrial providers. Subscriber percentages hinge at least partly on marketing strengths (cable operators have at least 70 percent of the installed base). 

U.S. ISP Population Coverage and Subscribers
Firm	Population %	Subscriber %
AT&T	42	15
Comcast	36	29
Charter	34	27
Verizon	17	7
Lumen	9	2
Cox Comm.	7	5
Altice	5	4

Still, the numbers suggest telcos have lower take rates than do cable operators, which corresponds to reality. Also, the telcos arguably have the greatest upside from network upgrades that would match or exceed cable performance metrics. With appropriate pricing, that should allow telcos to eventually close the take rate gap with cable companies, all other things being equal.
