AT&T sues to ditch Cali copper phone lines to save billions

AT&T wants to ditch its traditional copper phone line infrastructure in California in favor of fiber everywhere, claiming it has to spend $1 billion each year on a telephone network that a tiny percentage of customers use. The US telecoms giant announced plans this week to invest $19 billion in The Golden State between now and the end of the decade to bring fiber to more than 4 million additional households and businesses, upgrading customers to the newer infrastructure.
