Cable up to 64% of the market. For a decade, telcos held on to 45% of the market in the U.S. But AT&T and Verizon haven't upgraded almost half their lines, planning to go wireless only to 10's of millions of homes. (One network is cheaper than two.) The other U.S telcos have done even less, keeping dividends far higher than earnings and skimping on capex.
Customers are fleeing DSL networks that often are ten and fifteen years old. The U.S. has cable to 92%, with most offering 50 megs standard. Comcast's primary offering is 100 megabits and they just extended a gig of DOCSIS 3.1 to Boston and Philadelphia. Frontier lost 101,000 subs and Century 77,000. Verizon's once world-leading fiber network wasn't to prevent a loss of 23,000 customers. The saddest story is AT&T. They have added 5M lines of fiber the last two years and spent $67B on DirecTV, seeking an expanded customer base. Despite that, they lost 9,000 customers.
