The introduction of the original version of the product altered the habits of consumers when it comes to music listening. Some of the products released by the company with the brand name are the Video Walkman, the Walkman MP3 player as well as the Network Walkman. From its development up to March 2007, the trademark remained popular to music lovers. To know more about the product, it is best to begin with identifying the person behind the development of the Sony Walkman. History of the Trademark Who invented the Sony Walkman? According to reports, the first walkman was developed and designed by Nobutoshi Kihara, an audio division engineer at Sony, in 1978. The product was created for the personal use of the company’s co-chairman Akio Morita. The executive requested Kihara to develop a portable music player that he can use to listen to classical songs during his trips. Because of the efficiency and high quality performance of the product, Sony decided to introduce the music player to the public. The first batch of Sony Walkman was released in Japan in 1979.

The product became popular because it allowed two individuals to listen to music at the same time. Aside from this, another special feature of the product is that it can be used to record conversations because it has a built-in...
Who Invented the Typewriter?

Who Invented the Typewriter?...

Do you know who invented the typewriter? With the continuous emergence of mechanical gadgets like computer keyboards, you may have thought that the earlier products of geniuses that made life easier for those who write may be lost in memory. Not so. Keep in mind that without the person who invented the typewriter, these computer keyboards wouldn’t have been made and produced nowadays if not from an earlier proto-type in the form of a typewriter. The First Model That is why we need to give credit to Christopher Latham Sholes, an American mechanical engineer, who was able to invent the first known practical modern typewriter in 1866 together with some colleagues, Samuel Soulé and Carlos Glidden. This first version was patented in 1868. After thousands of experiments done in five years, and after having patented their inventions twice, Sholes, Soulé, and Glidden were able to have a more improved version that is actually similar to some of the current typewriter models. The QWERTY Standard With the earlier version made by Sholes and friends, the best feature of the typewriter that they consider is the type-bar system and its universal keyboard. But then, after sometime, with – perhaps – constant use, they noticed that the typewriter keys jammed. To help the situation, James Densmore, who was also a business associate of the group, made a good suggestion that would help the model work better. The suggestion involved splitting up the typewriter’s keys for specific letters of the alphabet that is usually used together to help slow down the process of typing. Later, this became known as the “QWERTY” keyboard that we now use in typewriters and also computer keyboards. The Product Market Since Sholes was not very patient enough –...
Who Invented Gunpowder?

Who Invented Gunpowder?

There is really no way to tell who invented gunpowder. Like a lot of the ancient inventions we enjoy today, gunpowder came about and was developed gradually through years of testing, use, and perfection. It is interesting that we can trace its origin several centuries into the past. In fact, you can trace the origin of gunpowder into the early days of ancient China. Early Origins Though we don’t know who invented gunpowder exactly we can find many people who have written about it and having it mentioned in their annals. One of the earliest records that mention anything like gunpowder dates back to 142 AD during China’s Han Dynasty. Wei Boyang is the first to have written something that described something like it. He wrote about a certain mixture that is made from three powders that dance and fly violently. Though he did not mention the word gunpowder what he describes is exactly what gunpowder is. We know that gunpowder is an explosive that does contain three foundational ingredients. We can thus surmise that the person who invented gunpowder lived prior to Boyang’s writing. Ge Hong, a scientist who lived during China’s Chin Dynasty around 300 AD wrote down the ingredients of gunpowder. Though having mentioned the ingredients he is not credited as the one who invented gunpowder. Ge Hong even went on to describe the explosion it makes. You mix the appropriate portions of sulfur, charcoal, and potassium nitrate to make it. People really began to put gunpowder to use in 700 AD during the T’ang Dynasty. The emperors during this dynasty used gunpowder in order to put up elaborate fireworks displays. But it was only in the year 904 AD when it was put to use...
Who Invented the Boom Box?

Who Invented the Boom Box?...

No one can say for certain who invented the boom box (also known as ghetto blaster). During the mid 1970s, the idea of a portable stereo became popular. A look at the history of the boom box reveals that Sanyo, Panasonic and Marantz were the pioneers. Cultural Impact The concept behind the boom box was that anyone could own a portable stereo system. While the idea first appeared in the 1970s, it really caught fire in the 1980s and early 1990s. During this period, young people could be seen carrying around boom boxes. Frequently one would see teenagers hanging around together with a boom box and dancing. This scenario would become even more widespread when breakdancing became popular. The emerging hip hp culture also contributed to the popularity of the boom box. There came a point when the boom box became a fashion statement as well. It wasn’t just the sound that mattered; it was the look, the buttons etc. But as an appraisal of the history of the boom box makes plain, the player would fade away in the 1990s. Technological innovations allowed for the invention of smaller audio players. The arrival of CD and mp3 players has greatly reduced the boom box’s popularity. Basic Features The boom box began its life as an extension for the radio cassette player. In the 1970s the cassette recorder became popular, but companies wanted to add AM/FM radio to it. Intense competition would lead to numerous innovations. The most basic features were a couple of speakers and an amplifier with radio tuner. The cassette player was also included. As the history of the boom box unfolded, the cassette player would be complemented (and replaced) by the CD component. The casing was...
Who Invented the Flash Drive?

Who Invented the Flash Drive?...

Introduction The USB flash drive is a tiny storage device that uses flash memory. It connects to a computer via a USB port. A flash drive is usually portable and rewritable. A single device can store anywhere from 64MB to 256GB and more depending on the model’s capacity. Because flash drives are so small and portable, they are ideal for carrying data while on the road. They can also be used to transfer data between two computers. Invention of the Flash Drive In the early days of the computer, things were much simpler. Files were small in size, so floppy disks were enough to store them in. But as computer technology advanced, so did the types of files used. Now floppy disks could only hold 1.44MB of data at a time and they were very slow. There was a need for a better portable storage device. It was IBM and Trek Technology who invented and sold the first USB flash drives in the year 2000. Trek Technology was a Singaporean company. They dubbed the new invention as a “thumb drive” because its size was roughly that of a thumb. In the US and Canada, IBM marketed a flash drive called “Disk On Key” which was made in Israel. The first flash drives had capacity of only 8MB. But this was already a huge leap from the 1.44MB capacity floppy disks in use at that time. Benefits of the Flash Drive The flash drive fulfills the same role as floppy disks, CD-RWs and other removable storage devices. They can be used to back up or transfer data. Floppy disks are now obsolete with new computers rarely carrying them. CD-RWs and other rewritable media are slower and more fragile. Flash drives...
Who Invented the Refrigerator?

Who Invented the Refrigerator?...

A study of the history of the refrigerator will reveal that the Scottish chemist William Cullen to be the first to use artificial refrigeration. He did it in Glasglow University in 1748. But the idea of preserving food using cool temperatures began much earlier. Early Experiments One of the earliest experiments was performed by Francis Bacon. In 1626 he thought of using snow to preserve chicken meat. He bought some chicken and filled it with snow. Unfortunately he got pneumonia and died within a few weeks. During this time, people kept food cold in icehouses. Even when Cullen made his demo in 1748, he didn’t follow it up. His experiment produced ice. But records on the history of the refrigerator show he never quite realized what it could mean. Around 1805, the American inventor Oliver Evans designed a refrigeration apparatus, but he didn’t build one. But the idea for the refrigerator caught on. The inventor Robert Perkins would improve on Evans’ creation and have his invention patented in 1834. But neither Perkins nor Evans’ machine were called a refrigerator. The word was first used by Thomas Moore in 1800. However his design was for a cedar tub. The tub was covered with rabbit fur and ice. While Moore called it a refrigerator, today it is more like an icebox. Modern History of the Refrigerator Perkins’ design made use of vapor compression, the first to do so. Its appearance is also more similar to modern refrigerators than the other inventions before. But the first home refrigerator was made by General Electric in 1911. The fridge was composed of wood. It was designed by Marcel Audiffen, a French physics teacher. In 1895 and 1908 he got the patents for the fridge...
