Cable-TV companies Charter Communications and Cox will merge, using Spectrum as the brand name, in an era of cord-cutting and streaming.

Two of the largest cable companies in the US are intent on merging. Charter Communications’ proposed acquisition of Cox Communications — the largest division of Cox Enterprises — will value the former at over $34 billion inclusive of debt.

Charter Communications on Friday agreed to buy privately held rival Cox Communications for $21.9 billion, combining two of the largest U.S. cable and broadband operators in their battle with streaming giants and mobile carriers.
