The original Kindle Fire retailed for  in 2011.
Estimates of the device's initial bill of materials cost ranged from $150 to $202. Amazon's business strategy was stated in 2011 as making money through sales of digital content on the Fire, rather than through sales of the device itself.

, the Kindle Fire was the second best selling tablet after Apple's iPad, with about 7 million units sold according to estimates by Forrester Research and  Amazon's tablets were the fourth best selling.

A more powerful and video-friendly version, the Kindle Fire HD (7 and 8.9 inch versions) was also made available, initially priced at $199 and $299.

On September 25, 2013, the Kindle Fire HD was upgraded as the third generation Fire, priced at , and the Kindle Fire HDX was introduced.

Design

Hardware 
The Kindle Fire hardware is manufactured by Quanta Computer (an Original Design Manufacturer), which also originally helped design the BlackBerry PlayBook, using it as a hardware template for the Kindle Fire.
First-generation Kindle Fire devices employed a 1-GHz Texas Instruments OMAP 4430 dual-core processor. The device has a 2-point multi-touch colour LCD screen with a diagonal length of  and a 600×1024-pixel resolution (160 dpi density). Connectivity is through 802.11n Wi-Fi and USB 2.0 (Micro-B connector). The device includes 8 GB of internal storage—said to be enough for 80 applications, plus either 10 movies or 800 songs or 6,000 books. According to Amazon, the first-generation Kindle Fire's 4400 mAh battery sustains up to 8 hours of consecutive reading and up to 7.5 hours of video playback with wireless off; later generations all offered around 7–8 hours

Of the 8 GB internal storage available in the first-generation Kindle Fire, approximately 6.5 GB was available for content.

The first-generation Kindle Fire has a sensor on the upper left-hand corner of the screen. This was widely considered to be an ambient-light sensor, disabled since an early software upgrade.

Colour display technologies consume much more power than monochrome electronic paper (E-ink) types; Fire offer a typical battery life of 8 hours of mixed usage,  while monochrome Kindles offer 15 to 30 hours' use without WiFi—"battery lasts weeks on a single charge"—with a much lower-capacity battery.

Software 
The first generation of Kindle Fire devices run a customised Android 2.3.3 Gingerbread OS. The second-generation Kindle Fire HD runs a customised Android 4.0.3 Ice Cream Sandwich OS. Along with access to Amazon Appstore, the Fire includes a cloud-accelerated "split browser", Amazon Silk, using Amazon EC2 for off-device cloud computation; including webpage layout and rendering, and Google's SPDY protocol for faster webpage content transmission. The user's Amazon digital content is given free storage in Amazon Cloud's web-storage platform, 5 GB music storage in Amazon Cloud Drive, and a built-in email application allows webmail (Gmail, Yahoo!, Hotmail, AOL Mail, etc.) to be merged into one inbox. The subscription-based Amazon Prime, which includes unlimited streaming of movies and TV shows, is available with a free 30-day trial period.

Content formats supported by the first-generation Kindle Fire were Kindle Format 8 (KF8), Kindle Mobi (.azw), TXT, PDF, unrestricted MOBI, PRC natively, Audible (Audible Enhanced (AA, AAX)), DOC, DOCX, JPEG, GIF, PNG, BMP, non-DRM AAC, MP3, MIDI, OGG, WAV, MP4, VP8.

Because of Amazon's USB driver implementation, the first-generation Kindle Fire suffered from slow USB transfer speeds. For example, transferring an 800MB video file may have taken more than three minutes in 2011.

It is possible to convert a Kindle Fire to a tablet running standard Android, with some loss of Amazon-related functionality, and lacking features such as Bluetooth, microphone, camera, and memory expansion.

Reception 
Analysts had projected the device to be a strong competitor to Apple's iPad, and that other Android device makers would suffer lost sales.

In a 2012 review published by Project Gutenberg, the Kindle Fire was called a "huge step back in freedom from the Kindle 3"; the reviewer noted that Amazon introduced a "deliberate limitation" into the Fire that didn't exist in the previous version: it is no longer possible to download free e-books from websites such as Project Gutenberg, Internet Archive and Google Books and have them stored permanently in the same places where books from Amazon are kept.

Sales 
Customers began receiving Kindle Fires on November 15, 2011; in December 2012, customers had purchased over a million Kindle devices per week. International Data Corporation (IDC) estimated that the Kindle Fire sold about 4.7 million units during the fourth quarter of 2011.

The Amazon Kindle Fire helped the company beat their 2012 first quarter estimates and boosted the company's stock in extended trading. As of May 2013, about 7 million units had been sold according to estimates. Statistics for FY2014 or Q1&2 2015 are not yet available.

Family 
Up to the present, there have been eleven generations of Fire tablets, spread across three different feature design lines: Fire, Fire HD and Fire HDX.

Beyond this usage, Fire is used for explicit phone devices and for TV add-on sticks.
