The late 1990s buildout of fiber-optic networks, in which companies spent billions to pull dark fiber across continents and under oceans, saw borrowers like WorldCom, Global Crossing, and others go under. The shale revolution that prompted U.S. oil and gas companies to issue $350 billion in debt to fund drilling led to hundreds of bankruptcies after oil prices swooned in 2014 and 2015. Going back even further to the early 1900s, the widespread adoption of electric power led to a buildout that saw roughly half of the 3,000 small utilities and power companies that existed either disappear or get sold during a brutal decade of consolidation.
