Name that company

I trace my roots back to 1993, when I was founded in St. Louis. I went on to acquire cable systems across the nation, but was deep in debt — and trouble — by 2009. I spent much of that year in Chapter 11 bankruptcy protection, but I emerged stronger. Microsoft co-founder Paul Allen held a controlling stake in me for about a decade. Today, with a market value recently near $136 billion, I’m a major telecom enterprise. I have the Spectrum brand, a network of more than 750,000 miles and more than 31 million customers in 41 states. Who am I?
