The First Mobile Phone

When we think about communication today, the first thing that comes to mind is the ubiquitous mobile phone. It's hard to imagine a time when cell phones didn't exist, but believe it or not, the first mobile phone call was made only in 1973. Motorola engineer Marty Cooper made history on April 3, 1973, when he made the first mobile phone call. It weighed a whopping 2.5 pounds and had a talk time of only 30 minutes.

The phone was far from perfect; in fact, it was quite clunky and inconvenient to use. However, it was the precursor to the sleek, compact smartphones that we take for granted today. The development of the mobile phone revolutionized the way that we communicate, enabling us to stay connected with each other no matter where we are in the world.

The Ethernet

The Ethernet is one of the most important inventions of the 20th century. It is a local area network (LAN) protocol that allows computers to communicate with each other within a single building or campus. It was invented by Bob Metcalfe at Xerox PARC in 1973.

Before the Ethernet, computers had to be connected via expensive and complicated systems. The Ethernet simplified the process, making it possible to connect computers in a more affordable and efficient way. Today, the Ethernet is the foundation of modern computer networks and is used in everything from corporate offices to home networks.

The Barcode Scanner

The barcode scanner is a device that is used to read and interpret barcodes. It was first patented in 1973 by Norman Woodland and Bernard Silver. A barcode is a series of lines and spaces that represent information. The scanner uses a laser to read the barcode and then sends the information to a computer.

The barcode scanner revolutionized the way that businesses operate. It made inventory management more efficient and accurate, allowing businesses to track their products with greater ease. Today, barcodes are used in a wide range of applications, from grocery stores to hospitals.

Innovations in Entertainment

The year 1973 saw a lot of groundbreaking innovations in the world of entertainment. Some of these inventions not only changed the way people experienced entertainment but also had a significant impact on the way technology developed in the years to come.

Compact Cassettes

Philips, a Dutch electronics company, introduced the compact cassette to the world in 1962, but it wasn't until the 1970s when it gained widespread popularity. The compact cassette was a more user-friendly audio recording medium in comparison to reel-to-reel tapes. Not only was it smaller and more portable, but it was also more affordable, which made it accessible to a broader audience. The compact cassette's popularity surged because it was not only easy to use and replace, but its excellent audio quality was a significant draw.

Unlike its predecessor, the reel-to-reel tapes, the compact cassette featured more stable tape speeds, which eliminated the previous humming and hissing from the playback sound. The cassette tape had two sides, with each side having up to 30 minutes of recording time. This innovation meant that people had the freedom to choose from a wide range of pre-recorded cassettes or create their own music mixtapes, which was a significant trend in the 1980s.

Electronic Dartboard

Do you ever feel like you're not getting points for hitting the bullseye? In 1973, Arachnid released the first electronic dartboard, which eliminated the need for manual scoring. The electronic dartboard featured a matrix of holes that used sensors to detect where the darts landed. The board kept score electronically, alleviating the need for manual scorekeeping. Arachnid's electronic dartboard quickly became a hit with bar-goers and provided a new level of game experience that was not previously possible.

The invention of electronic dartboards meant that multiple players could compete using the same arrow and eliminated the need for every player to have their own set of darts. Additionally, electronic dartboards could track more than just scores, allowing players to keep track of individual statistics like averages and best throws for more personal motivation and competition.

Video Game Console

The Magnavox Odyssey² was the first video game console to be connected to televisions, marking a significant step in the evolution of gaming.

New Technologies in Science and Engineering

In 1973, several groundbreaking innovations in technology were introduced that continue to impact our daily lives today. From improving the efficiency of retail sales to revolutionizing computer memory, these new technologies changed the way we think about information and data storage. Here are three significant inventions from 1973 that advanced technology in science and engineering.

Universal Product Code (UPC)

The Universal Product Code (UPC) was introduced in 1973 and quickly became an essential part of retail sales. It is a system for identifying products with a barcode that made the checkout process much faster and more accurate. The barcode consists of a series of vertical lines that represent a unique number for each product. When the cashier scans the barcode, the information is immediately linked to the computer system, which can then calculate the price, inventory, and other important data related to the product.Before the UPC was introduced, retail stores used a manual system that was often inaccurate and time-consuming. The introduction of the UPC changed all that. It allowed stores to manage inventory more efficiently and prevented pricing errors. This system has since been expanded to include other information, such as expiration dates and lot numbers.The Universal Product Code (UPC) has greatly revolutionized retail sales, making it easier for customers to purchase the products they need quickly and efficiently.

Dynamic Random-Access Memory (DRAM)

In 1973, Dynamic Random-Access Memory (DRAM) was introduced, replacing older magnetic-core memory systems with a faster, more reliable design. DRAM is a type of computer memory that is used to temporarily store data that is currently in use.The primary advantage of DRAM is its speed; it can retrieve and store data incredibly fast. This made it an ideal replacement for magnetic-core memory systems, which were slower and less reliable.DRAM uses tiny capacitors to store data instead of transistors, which the older memory systems used. It has now become one of the most common forms of computer memory and is used in a wide range of applications, from laptops to servers.

The IBM 3340 Hard Drive

The IBM 3340 hard drive was introduced in 1973 and dramatically increased the storage capacity of computers of that time. It could hold up to 70MB of data, which was a significant improvement over older storage devices.One of the most significant changes the IBM 3340 introduced was the concept of non-removable media. Prior to its introduction, most data storage devices were removable, such as floppy disks. The IBM 3340 hard drive revolutionized data storage by making it unnecessary to remove the media from the drive, thereby reducing errors and increasing efficiency.The IBM 3340 hard drive also introduced the concept of error-correcting code (ECC) to data storage. This made it possible for computers to detect and correct errors that occurred during the transfer of data. This increased the accuracy of data storage and retrieval, making it possible to store and access more data than ever before.In conclusion, the inventions of 1973 have had a significant impact on the way we store and retrieve data, making it quicker and more efficient. With the Universal Product Code (UPC), Dynamic Random-Access Memory (DRAM), and the IBM 3340 hard drive, we have revolutionized retail sales, computer memory, and data storage. These inventions serve as a testament to human ingenuity and our ability to improve the world through technology.

Innovations in Health and Medicine

In 1973, several groundbreaking inventions in the field of health and medicine were introduced to the world, revolutionizing the way doctors and patients treated and diagnosed medical conditions. These innovations have contributed significantly to modern medicine, saving countless lives and making medical procedures less invasive and more efficient.

The CT Scan

The computed tomography (CT) scanner was invented in 1973 by Godfrey Hounsfield and Allan Cormack, which eventually led to them receiving the Nobel Prize. The CT scan is a non-invasive medical imaging technique that allows doctors and medical professionals to view detailed images of the body's internal structures, including organs, bones, and soft tissues. This technology is valuable in diagnosing and treating various medical conditions, including cancer, heart disease, and bone injuries.

Prior to the development of the CT scan, traditional X-rays could only provide two-dimensional images, making it difficult to make accurate diagnoses. The CT scan revolutionized medical imaging by producing cross-sectional images of the body, allowing doctors to see detailed pictures of organs, bones, and soft tissues from different angles. This made it easier for doctors to detect and diagnose medical conditions, leading to better treatment outcomes for patients.

The Virtual Colonoscopy

In 1973, the virtual colonoscopy was invented as a non-invasive alternative to the traditional colonoscopy, which required sedation and a long recovery period. A virtual colonoscopy uses CT scanning technology to create a 3D image of the colon, eliminating the need for the traditional invasive procedure.

A virtual colonoscopy involves inserting a tube into the rectum, which pumps air into the colon to inflatethe organ so that the CT scanner can capture detailed images. This procedure is less invasive, and patients are allowed to resume their normal activities immediately after the exam, unlike the traditional colonoscopy, which requires sedation and a more extended recovery period.

The virtual colonoscopy has made colon cancer screening more accessible and less invasive, helping to increase the number of patients who undergo screening. Since polyps can be detected and removed before they become cancerous, the virtual colonoscopy has led to earlier diagnoses of colon cancer, saving countless lives.

The Embolization Procedure

The embolization procedure was developed in 1973 to treat uterine fibroids and other conditions that affect the body's blood vessels. This procedure involves inserting a thin tube into the affected area and blocking the blood supply by injecting tiny particles. This cuts off the blood supply to the impacted part of the body, resulting in the shrinkage of the affected area.

The embolization procedure is a less invasive alternative to traditional surgery, which has a longer recovery time and more risks. This procedure is also usefulin treating other conditions, including tumors, vascular malformations, and varicoceles. The embolization procedure has improved the quality of life for many patients, helping them to avoid more invasive procedures and minimizing the risk of complications.


These inventions in the field of medicine have been groundbreaking and have significantly impacted the medical industry. From the CT scan to the virtual colonoscopy and the embolization procedure, these innovations have made medical procedures less invasive and provided higher-quality medical imaging, resulting in more accurate diagnoses and treatment of medical conditions. These inventions have improved countless lives, and they continue to be critical tools in modern medicine.
