Purely electronic circuit elements soon replaced their mechanical and electromechanical equivalents, at the same time that digital calculation replaced analog. The engineer Tommy Flowers, working at the Post Office Research Station in London in the 1930s, began to explore the possible use of electronics for the telephone exchange. Experimental equipment that he built in 1934 went into operation 5 years later, converting a portion of the telephone exchange network into an electronic data processing system, using thousands of vacuum tubes. In the US, John Vincent Atanasoff and Clifford E. Berry of Iowa State University developed and tested the Atanasoff–Berry Computer (ABC) in 1942, the first "automatic electronic digital computer". This design was also all-electronic and used about 300 vacuum tubes, with capacitors fixed in a mechanically rotating drum for memory.

In March 2013, Governor Rick Snyder declared a financial emergency in the city, stating that the city has a $327 million budget deficit and faces more than $14 billion in long-term debt. It has been making ends meet on a month-to-month basis with the help of bond money held in a state escrow account and has instituted mandatory unpaid days off for many city workers. Those troubles, along with underfunded city services, such as police and fire departments, and ineffective turnaround plans from Bing and the City Council led the state of Michigan to appoint an emergency manager for Detroit on March 14, 2013. On June 14, 2013 Detroit defaulted on $2.5 billion of debt by withholding $39.7 million in interest payments, while Emergency Manager Kevyn Orr met with bondholders and other creditors in an attempt to restructure the city's $18.5 billion debt and avoid bankruptcy. On July 18, 2013, the City of Detroit filed for Chapter 9 bankruptcy protection. It was declared bankrupt by U.S. judge Stephen Rhodes on December 3, with its $18.5 billion debt he said in accepting the city's contention that it is broke and that negotiations with its thousands of creditors were infeasible.

Yale is organized into fourteen constituent schools: the original undergraduate college, the Yale Graduate School of Arts and Sciences, and twelve professional schools. While the university is governed by the Yale Corporation, each school's faculty oversees its curriculum and degree programs. In addition to a central campus in downtown New Haven, the University owns athletic facilities in western New Haven, including the Yale Bowl, a campus in West Haven, Connecticut, and forest and nature preserves throughout New England. The university's assets include an endowment valued at $25.6 billion as of September 2015, the second largest of any educational institution.The Yale University Library, serving all constituent schools, holds more than 15 million volumes and is the third-largest academic library in the United States.
