What is Spectrum? Charter Spectrum, or simply Spectrum, is a new name to many parts of the country. Spectrum is the brand name for cable, Internet and phone service from Charter Communications.
Although Charter started using the Spectrum name prior to its merger, the name Spectrum gained prominence as a result of the second, fourth, and sixth-largest cable operators in the United States merging in 2016. Post-merger Charter is now a Fortune 100 company.
