The electronics industry, especially in its correlation with consumer electronics, has its first conception far back to the early 20th century. Today, the industry sector has been a global enterprise worth billions of dollars. At this rate, pretty much all members of society have used all forms of electronic devices which are built in factories the industry operates that are either automated or semi-automated. Integrated circuits form the foundation for the assembly of those electronic devices, made through the process of photo lithography of printed circuit boards. But the electronics industry is far from being flawless, though. Concerns come from the difficulty of recycling, the use of toxic materials, and the size of the industry, all of which pose a vast array of problems with electronic waste. Several international regulation and environmental legislation have been in the work for some time in an attempt to address possible issues originating from this industry sector.
The electronic industry in general began its life with the development of electric power industry in the 19th century. The invention of electricity-based power generating system opened a door to the invention of a host of all sorts of other devices. In the beginning, there were gramophones, whose existence led to the invention of radio transmitters and receivers and televisions. In the 1940s, the first digital computers were invented but its development in total sales and technology was slow.
The vacuum tube was replaced with semiconductor components in both the 1970s and 1980s, serving as the fundamental application within the industry. Personal computers became a popular staple in the 1990s. Today, a sizeable portion of the electronics industry makes use of digital technology. The industry sector today is composed of electronics engineers and electronics technicians, all of who work in the design, development, test, manufacturing, installation, and repair of electrical and electronic devices such as computers, navigational equipment, medical monitoring devices, and communication equipment. Parts and components that are commonly manufactured include computer accessories, cell systems, system components, and connectors, which are produced using steel tubing, plastic, stainless steel, brass, copper, and alloy steel, among others.
Consumer electronics as an industry are defined as products that are meant for everyday use in areas such as office productivity, communications, and entertainment. The first major consumer product was presented in the early 20th by radio broadcasting in the form of broadcast receiver. Later examples include PCs, telephones, MP3 players, audio equipment, televisions, calculators, and digital cameras.
