The device was released on 3 May 2012 in London, and was anticipated to be the greatest competitor to Apple's iPhone 4S.  The Galaxy S III has been the target of some political litigation since its release, especially with the Apple corporation regarding possible intellectual property rights infringement.
In 1939, founder Lee Byung Chul started Samsung as a small trade company that consists of just 40 employees selling groceries and homemade noodles. After the Korean War broke out in 1950, Lee started a woolen mill factory, which eventually became the largest textile producer in Korea. Following the success of woolen mill, Lee expanded his business to different areas such as insurance, security, and retail. Samsung entered the electronics industry in the late 1960s, with the production of their first black-and-white television. Presently, Samsung has become a multinational conglomerate company in South Korea, employing over 42,000 people. The company comprises numerous subsidiaries and affiliated businesses, most of which are united under the Samsung brand.  From its start in 1939, Samsung has grown into one of the largest companies worldwide and continues to reach new feats such as developing the world's first 50 nanometers 16GB NAND flash memory and debuting the world's first cinema LED Screen. Samsung's technological progress and the release of new devices helped bring it to the number 6th company in Interbrand's Best Global Brands in 2017. 
The Galaxy S III was originally released with Android 4.0.4 (Ice Cream Sandwich). Samsung has updated the Galaxy S III to the Android 4.1 "Jelly Bean", the latest version of the Android platform, on most US carriers including AT&T and T-Mobile. The phone has not yet been updated for Verizon customers, however.

The Galaxy S3 has a number of features that enable the sharing of information. One of these features is called Near Field Communication (NFC) and is similar to Radio-frequency Identification (RFID) but with a shorter range. NFC isn't new, but as of now, it is not quite wide spread in the United States. NFC uses electromagnetic radio field to transmit information or read NFC tags that contain information. NFC, not only allows sharing information with other people but also allows "sharing" other information such as credit card information with devices to purchase goods.
S beam - This feature allows for the sharing of pictures, music, and videos by placing to NFC enabled phones back-to-back.
AllShare Cast - This feature lets users project whatever is on the Galaxy S3's screen onto a bigger screen and even will let users use their phones as a universal remote.
AllShare Play - This feature is similar to bluetooth and will allow users to connect and share with other devices even when away from your computer. This feature may be used through Wi-Fi.
Buddy Photo Share - This feature will recognize the faces in pictures you take and will automatically share the picture with the people tagged.

Some of the major competitors are:
The Galaxy S III attempted to win over customers to buy their phone instead of their competitors by creating and expanding on a bold and expensive advertising campaign, particularly through television commercials. At the time of the iPhone 5 release in September 2012, Samsung tried swaying its potential customers by noting through their slogan that "the next big thing is already here." Samsung displayed confidence in its product by highlighting aspects of the Galaxy S III that were different than what its competitors had to offer. One of Samsung's more agressive commercials Samsung Attack on Apple, attacked apple's iphone 5 (thier most fierce competitor) with sarcastic lines such as "the headphone jack is going to be on the bottom" and reiterating the good quality of the new iphone adapter. This focuses on apple's new aspects and features to be less innovating and legitamate as Samsung's new galaxy s3.
The Galaxy S III is the successor of two prior Galaxy phones from Samsung.
The Galaxy S is the first predecessor of the Galaxy S III. It was first launched in South Korea in June of 2010, followed by 100 countries on 110 carriers. It was named number 2 in Time’s Top Ten Gadgets of the Year list in 2010. The Galaxy S received praise for its Super AMOLED display, boasting a 20% brighter display, its speed at the time, its memory capacity, its extended battery life, and its size. The Galaxy S uses the “Hummingbird” Processor, making it the fastest Android at the time. Samsung also claimed it was the thinnest touchscreen phone, measuring at 9.9mm deep. Criticism for the Galaxy S was based on its lack of 4G Network availability and its 5mp camera, while competitors such as the Sprint EVO 4G supported 4G data and had an 8mp camera.
Galaxy S II
The Galaxy S II is the most recent predecessor of the Galaxy S III. It was first launched in May of 2011 by Samsung, and is now sold in over 140 countries on 120 carriers. It received high ratings globally and was named the “The Smartphone of the Year 2012” in the Global Mobile Awards. It was praised for its bright screen with the Super AMOLED display, its fast processor, and for being one of the slimmest smartphones, measuring in at only 8.49mm deep. Criticisms of the phone include the location of the speaker, the very large screen (4.3 in), and the moderate battery life.
Starting with an initial complaint filed April 15, 2011, Apple Inc. filed a series of lawsuits against Samsung Electronics in patent infringement suits. Apple claimed Samsung infringed its intellectual property rights by improper use of Apple's trademark, patents, user interface, and style in developing Samsung products, including the Samsung S3. 
Samsung counter-sued Apple on April 22, 2011, claiming Apple copied Samsung mobile-communications technology. Litigation between Samsung and Apple Inc. encompassed 19 cases in 10 countries. Apple won a favorable ruling in the United States; however, rulings in South Korea, Japan, the UK, were ruled in favor of Samsung. Additionally, the rulings in Germany and Netherlands were dismissed, and a hearing is scheduled to be held for Australian courts in late December 2012. 
On August 24, 2012, the United States jury ruled in favor of Apple, finding Samsung guilty of willful infringement on 6 out of 7 accusations. The six patents included technical features such as Pinch and Zoom, Bounce-back effect, Drag documents, On-screen navigation and Scroll using one finger. Additionally, design features, including the home button, rounded corners and edges and on screen icons were cited as part of the infringement by Samsung. The final damages determined by the jury to be provided to Apple amounted to $1.049 billion.
The Bounce-back effect patent filed by Apple was invalidated on October 23, 2012, and may affect further ruling concerning the lawsuits against Samsung. 
Interpretation of the Litigation Verdict
The ruling in the Samsung vs. Apple lawsuits, particularly concerning the United States ruling, raised several questions concerning the competition within and consumer impact upon the smartphone industry. Successful prosecution by Apple had little effect on their overall business practice, and collected royalties from those willing to use Apple patents.
Samsung was forced to halt sales of phones infringing upon the violations outlined in the United States litigation, as well as in other countries. However, Samsung has since claimed jury misconduct on the part of the United States court ruling, as one jury member was later found out to be an electrical engineer and patent holder who had been sued by his former employer, also a major electronics company. 
As of December 3rd, 2012, the United States Patent and Trade Office (USPTO) has reviewed and found a key Apple multitouch patent to be invalid, rejecting all 20 claims of touch screen patent '949. The patent is referred to as the "Steve Jobs Patent" because Jobs is the first named inventor on the patent. The patent was challenged back in 2010 for a reexamination of its ruling, but the USPTO rejected the request. It is unclear at the moment how Samsung will be affected by this patent infringement reversal.
