I didn't believe it until I double-checked the figures. Telefonica Spain added 500,000 homes passed by fibre to the home in Q1 2018 to reach 19.7M. Three months later, they are almost certainly over 20M, over 75% of Spain. They are now making more money per customer (EBITDA,) seeing less churn, and reducing operating expenses on the new network. The financial results were so favorable the Brazilian subsidiary, VIVO, is also adding 7M. VIVO's total will be 14M by 2020.
Across Europe, iDate and the Fibre to the Home Council calculate FTTB/FTTH rose by 20% in 2017. British Telecom and Deutsche have fone very little do far but have planned over 20M lines starting in 2019. Below, the iDate/FTTH charts for all of Europe. The trend is obvious.
