For more than three decades, Apple Computer was predominantly a manufacturer of personal computers, including the Apple II, Macintosh and Power Mac lines, but it faced rocky sales and low market share during the 1990s. Apple was established on April 1 1976 by Steve Jobs, Steve Woznaik and Ronald Wayne to sell the personal computer kit known as Apple I. The name of the company came when Steve Jobs was working in the orchards in Oregon. The reason of the word may be because there were many apples in the orchard and the word just occurred to him. After this, they tried to come up with many other names but no name seemed better than Apple.
The development of iPhone began in 2004 when a team of 1000 employees gathered together to work on a highly confidential project known as "Project Purple". The phone was developed at an estimated development cost of US $150 million over thirty months. The phone was unveiled to public on 9th January 2007 by Steve Jobs at Moscone Centre in San Francisco with two initial models, a 4GB model priced at US$499 and an 8GB model priced at US$599. The first 'i-phones' went on sale on 29th June 2007. The reaction to the phone was very positive and hundreds of customers lined up outside stores. The public response was captured by some sections of media as the 'Jesus phone'. After the successful release in USA, iPhone was made available in the UK, France and Germany in November 2007 and Ireland and Austria in 2008. The second generation of iPhones were released with iPhone 3G along with GPS. This led to the Apple tradition of adding 'S' to the end of the name for a minor iPhone upgrade and the 2009 model of iPhone brought the video recording capabilities for the first time and the camera also got an upgrade. The 'S' stood for speed and reflected the improvements in the components. The next launch was in June 2010 with iPhone 4 which had a new sleeker more modern look and massive increased pixel count on the same 3.5 inch display size. This was the first phone with Retina display and a front facing camera and it was also the first iPhone with some level of multitasking. In 2011, Apple swung back to the minor 'S' upgrade with iPhone 4S. The upgraded model came with a camera upgrade to 8 megapixels and the biggest improvement on the software of iOS 5.0. Siri, the digital assistant of Apple iPhones was also introduced with the same model. This voice modulated digital assistant now plays a major role in iPhone. The next launch was in September 2012 and iPhone 5 was introduced. It added an extra row of icons with an extra-tall screen, introduced the lightning connector and had a lighter aluminum casing. It also introduced Apple Maps which took over from Google Maps as the default option. In 2013, Apple decided to start releasing two iPhones every September and the iPhone 5C was the successor of iPhone 5 with a few changes and gave its buyer the option to buy cheaper variant of the brand. iOS 7 was launched at the same time which resulted in multitasking for apps and introducing the Control Centre for more convenient access to iPhone's settings. iPhone 5S was released at the same time and it was the flagship model for 2013 with a revamped design and a little feature called Touch ID introduced to the iPhone line up for the first time. Another first was a 64-bit A7 processor inside the phone, an architectural change that other manufacturers have since followed.
The next launch was of iPhone 6 on September 2014 and it extended the display size to 4.7 inches and added more pixels to boot. It introduced the NFC for Apple Pay and other services plus a significant upgrade for the camera giving better photo and video results than ever before. The next launch was of iPhone 6 plus with a display of 5.5 inches, from corner to corner and it was a big phone and even got closer to the iPad Mini. It was almost similar to iPhone 6 and had a little extra thickness and weight. iPhone 7 was launched on September 2016 and will be available for sale with a price of Rs 60,000 in India. The iPhone 7 comes with a 4.7-inch display with 750x1344 resolutions at a pixel density of 326 pixels per inch. The iPhone 7 is powered by quad-core Apple A10 Fusion SoC and it comes with 32GB/ 128GB/ 256GB storage options. In terms of camera, the Apple iPhone 7 sports a 12-megapixel primary camera and a 7-megapixel front shooter for selfie profiles.
