Why Charter Communications Is Focusing on DOCSIS 3.1 Technology



Charter’s high-speed Internet business

A core growth driver of Charter Communications’ (CHTR) residential service component in the second quarter was its high-speed Internet business. Charter continues to be optimistic about the business’s growth trajectory, as high-speed Internet demand is growing as people are migrating to Internet television services such as Alphabet’s (GOOGL) YouTube TV, Amazon (AMZN) Prime Video, and Netflix (NFLX). In the second quarter, Charter Communications added 218,000 residential net broadband customers, representing a 5.2% fall YoY (year-over-year) from 230,000.
