Cordwood construction can save significant space and was often used with wire-ended components in applications where space was at a premium (such as missile guidance and telemetry systems) and in high-speed computers, where short traces were important. In cordwood construction, axial-leaded components were mounted between two parallel planes. The components were either soldered together with jumper wire, or they were connected to other components by thin nickel ribbon welded at right angles onto the component leads. To avoid shorting together different interconnection layers, thin insulating cards were placed between them. Perforations or holes in the cards allowed component leads to project through to the next interconnection layer. One disadvantage of this system was that special nickel-leaded components had to be used to allow the interconnecting welds to be made. Differential thermal expansion of the component could put pressure on the leads of the components and the PCB traces and cause physical damage (as was seen in several modules on the Apollo program). Additionally, components located in the interior are difficult to replace. Some versions of cordwood construction used soldered single-sided PCBs as the interconnection method (as pictured), allowing the use of normal-leaded components.

Development of the methods used in modern printed circuit boards started early in the 20th century. In 1903, a German inventor, Albert Hanson, described flat foil conductors laminated to an insulating board, in multiple layers. Thomas Edison experimented with chemical methods of plating conductors onto linen paper in 1904. Arthur Berry in 1913 patented a print-and-etch method in Britain, and in the United States Max Schoop obtained a patent to flame-spray metal onto a board through a patterned mask. Charles Ducas in 1927 patented a method of electroplating circuit patterns.

The Austrian engineer Paul Eisler invented the printed circuit as part of a radio set while working in England around 1936. Around 1943 the USA began to use the technology on a large scale to make proximity fuses for use in World War II. After the war, in 1948, the USA released the invention for commercial use. Printed circuits did not become commonplace in consumer electronics until the mid-1950s, after the Auto-Sembly process was developed by the United States Army. At around the same time in Britain work along similar lines was carried out by Geoffrey Dummer, then at the RRDE.

During World War II, the development of the anti-aircraft proximity fuse required an electronic circuit that could withstand being fired from a gun, and could be produced in quantity. The Centralab Division of Globe Union submitted a proposal which met the requirements: a ceramic plate would be screenprinted with metallic paint for conductors and carbon material for resistors, with ceramic disc capacitors and subminiature vacuum tubes soldered in place. The technique proved viable, and the resulting patent on the process, which was classified by the U.S. Army, was assigned to Globe Union. It was not until 1984 that the Institute of Electrical and Electronics Engineers (IEEE) awarded Mr. Harry W. Rubinstein, the former head of Globe Union's Centralab Division, its coveted Cledo Brunetti Award for early key contributions to the development of printed components and conductors on a common insulating substrate. As well, Mr. Rubinstein was honored in 1984 by his alma mater, the University of Wisconsin-Madison, for his innovations in the technology of printed electronic circuits and the fabrication of capacitors.

Originally, every electronic component had wire leads, and the PCB had holes drilled for each wire of each component. The components' leads were then passed through the holes and soldered to the PCB trace. This method of assembly is called through-hole construction. In 1949, Moe Abramson and Stanislaus F. Danko of the United States Army Signal Corps developed the Auto-Sembly process in which component leads were inserted into a copper foil interconnection pattern and dip soldered. The patent they obtained in 1956 was assigned to the U.S. Army. With the development of board lamination and etching techniques, this concept evolved into the standard printed circuit board fabrication process in use today. Soldering could be done automatically by passing the board over a ripple, or wave, of molten solder in a wave-soldering machine. However, the wires and holes are wasteful since drilling holes is expensive and the protruding wires are merely cut off.

Despite significant European success during the 1970s and early 1980s, the late '80s had marked a low point for English football. Stadiums were crumbling, supporters endured poor facilities, hooliganism was rife, and English clubs were banned from European competition for five years following the Heysel Stadium disaster in 1985. The Football League First Division, which had been the top level of English football since 1888, was well behind leagues such as Italy's Serie A and Spain's La Liga in attendances and revenues, and several top English players had moved abroad.

However, by the turn of the 1990s the downward trend was starting to reverse; England had been successful in the 1990 FIFA World Cup, reaching the semi-finals. UEFA, European football's governing body, lifted the five-year ban on English clubs playing in European competitions in 1990 (resulting in Manchester United lifting the UEFA Cup Winners' Cup in 1991) and the Taylor Report on stadium safety standards, which proposed expensive upgrades to create all-seater stadiums in the aftermath of the Hillsborough disaster, was published in January of that year.

Television money had also become much more important; the Football League received £6.3 million for a two-year agreement in 1986, but when that deal was renewed in 1988, the price rose to £44 million over four years. The 1988 negotiations were the first signs of a breakaway league; ten clubs threatened to leave and form a "super league", but were eventually persuaded to stay. As stadiums improved and match attendance and revenues rose, the country's top teams again considered leaving the Football League in order to capitalise on the growing influx of money being pumped into the sport.

At the close of the 1991 season, a proposal was tabled for the establishment of a new league that would bring more money into the game overall. The Founder Members Agreement, signed on 17 July 1991 by the game's top-flight clubs, established the basic principles for setting up the FA Premier League. The newly formed top division would have commercial independence from The Football Association and the Football League, giving the FA Premier League licence to negotiate its own broadcast and sponsorship agreements. The argument given at the time was that the extra income would allow English clubs to compete with teams across Europe.

The managing director of London Weekend Television (LWT), Greg Dyke, met with the representatives of the "big five" football clubs in England in 1990. The meeting was to pave the way for a break away from The Football League. Dyke believed that it would be more lucrative for LWT if only the larger clubs in the country were featured on national television and wanted to establish whether the clubs would be interested in a larger share of television rights money. The five clubs decided it was a good idea and decided to press ahead with it; however, the league would have no credibility without the backing of The Football Association and so David Dein of Arsenal held talks to see whether the FA were receptive to the idea. The FA did not enjoy an amicable relationship with the Football League at the time and considered it as a way to weaken the Football League's position.

In 1992, the First Division clubs resigned from the Football League en masse and on 27 May 1992 the FA Premier League was formed as a limited company working out of an office at the Football Association's then headquarters in Lancaster Gate. This meant a break-up of the 104-year-old Football League that had operated until then with four divisions; the Premier League would operate with a single division and the Football League with three. There was no change in competition format; the same number of teams competed in the top flight, and promotion and relegation between the Premier League and the new First Division remained the same as the old First and Second Divisions with three teams relegated from the league and three promoted.
