History of Bluetooth
Harald I Bluetooth (Danish Harald Blåtand) was the King of Denmark between 940 and 985 AD. The name "Blåtand" was probably taken from two old Danish words, 'blå' meaning dark skinned and 'tan' meaning great man. He was born in 910 as the son of King Grom The Old (King of Jutland, the main peninsula of Denmark) and his wife Thyre Danebold (daughter of King Ethelred of England). Like many Vikings, Harald considered it honorable to fight for treasure in foreign lands. When Harald's sister Gunhild was widowed after the death of the violent Norwegian king Erik Blood Axe, she came to Denmark to seek Harald's help in securing control of Norway. Harald took the opportunity to seize control himself. By 960 he was at the height of his powers, ruling over both Denmark and Norway. He was baptized by a priest named Poppo, sent by the German emperor. He then created a monument that read: "King Harald raised this monument to the memory of Grom his father and Thyre his mother. Harald conquered all of Denmark and Norway and made the Danes Christian". These words were also carved in stone called rune stones. Harald was killed in a battle in 985. Harald completed the country's unification begun by his father, converted the Danes to Christianity, and conquered Norway. The expansion begun by Harald in Norway was continued by his son Sweyn I, who conquered England in 1013. Under Sweyn's son Canute there grew up a great Anglo-Scandinavian kingdom that included parts of Sweden.
Old Harald Bluetooth united Denmark and Norway, Bluetooth of today will unite the worlds of computers and telecom (hopefully longer than the few years Harald's Viking kingdom survived). In 1994 Ericsson Mobile Communications initiated a study to investigate the feasibility of a low-power low-cost radio interface between mobile phones and their accessories. In Feb 1998, five companies Ericsson, Nokia, IBM, Toshiba and Intel formed a Special Interest Group (SIG). The group contained the necessary business sector members - two market leaders in mobile telephony, two market leaders in laptop computing and a market leader in digital signal processing technology. It is estimated that before year 2002, Bluetooth will be a built-in feature for more than 100 million mobile phones and several million communication devices ranging from handsets and portable PCs to desktop computers and notebooks.

History of USB Pen Drives
USB pen drive or flash drive uses a tiny PCB (Printed Circuit Board) to store large amounts of data and its data storage is based on EEPROM technology which has undergone many changes since it was first used. Although, the first ever pen drive which is also known as Thumb Drive was rolled out by Trek, a computer hardware manufacturing company in market in 2000, other companies developed and started to sell similar type of devices in the market during this period.
Early developments of Flash Drives
Between 1998 and 2001, SanDisk, which was formerly known as M-Systems, was involved in developing DiskOnKey and USB flash drive. M-Systems sold their USB type devices under the names like DiskOnKey and Diskey. In early 2000, Lexar, another company introduced some new features with their USB drives like Compact Flash, memory card reader and USB cable. These new features helped to access the data without using external USB devices like USB Hub.|
IBM was also a pioneer in USB flash drive and its documentation of the USB Flash drive and its functions helped the manufacturers to develop the pen drive and introduce new features. Initially, M-Systems worked closely with IBM and produced DiskOnKey for IBM before it introduced it in the commercial market in 2000. The first DiskOnKey had a capacity of 8 MB. Shimon Shmueli who was closely associated with IBM, launched his own company, KeyNetica. This company developed the small storage devices that can be used with PCs and can be convenient for easy transportation. Later, SanDisk bought the rights of manufacturing these devices and developed U3 and Ceedo, the advanced concepts of USB drives.
