Charter Communications
Next to Comcast, Charter Communications is the leading cable provider in the United States. The Stamford, Connecticut-based company, which offers internet and TV services too in its Spectrum line, acquired Time Warner Cable in a $56.7-billion deal and Bright House for $10.4 billion in 2016.
Warren Buffett has been a firm backer of Charter Communications, being an investor of the company since 2014. Gladstone Capital Management, worth at least $1.81 billion as of February 2021, has allocated big money for the cable company, now almost accounting for 1.9 percent of its portfolio.
