Access Industries’ full stack music company has, ahem, company: Liberty Media. With a combined market market cap of $37 billion John Malone’s Liberty group of companies is by anyone’s standards is a serious player. In the world of media and telecoms it is one of the biggest. Liberty grabbed the headlines this week with its $2.7 billion acquisition of a 15% stake in Formula One, with an option to acquire the entire company, possibly by year’s end. It is a typically bold move for a company that makes a habit of acquiring companies and consolidating markets. Over the past 11 years Liberty Media and Liberty Global have spent around $50 billion on acquiring companies such as UK TV operator Virgin Media, Dutch cable company Ziggo and (indirectly via a holding company) major league baseball team Atlanta Braves.
