E-reader
An e-reader, also called an e-book reader or e-book device, is a mobile electronic device that is designed primarily for the purpose of reading digital e-books and periodicals.Any device that can display text on a screen may act as an e-reader; however, specialized e-reader devices may optimize portability, readability, and battery life for this purpose. Their main advantage over printed books is portability. This is because an e-reader is capable of holding thousands of books while weighing less than one book, and the convenience provided due to add-on features.
Overview
An e-reader is a device designed as a convenient way to read e-books. It is similar in form factor to a tablet computer, but often features electronic paper rather than an LCD screen. This yields much longer battery life — the battery can last for several weeks — and better readability, similar to that of paper even in sunlight. Drawbacks of this kind of display include a slow refresh rate and (usually) a grayscale-only display, which makes it unsuitable for sophisticated interactive applications as those found on tablets. The absence of such apps may be perceived as an advantage, as the user may more easily focus on reading. The Sony Librie, released in 2004 and the precursor to the Sony Reader, was the first e-reader to use electronic paper.Many e-readers can use the internet through Wi-Fi and the built-in software can provide a link to a digital Open Publication Distribution System (OPDS) library or an e-book retailer, allowing the user to buy, borrow, and receive digital e-books. An e-reader may also download e-books from a computer or read them from a memory card. However, the use of memory cards is decreasing as most of the 2010s era e-readers lack a card slot.
History
An idea similar to that of an e-reader is described in a 1930 manifesto written by Bob Brown titled The Readies, which describes "a simple reading machine which I can carry or move around, attach to any old electric light plug and read hundred-thousand-word novels in 10 minutes". His hypothetical machine would use a microfilm-style ribbon of miniaturized text which could be scrolled past a magnifying glass, and would allow the reader to adjust the type size. He envisioned that eventually words could be "recorded directly on the palpitating ether".The establishment of the E Ink Corporation in 1997 led to the development of electronic paper, a technology which allows a display screen to reflect light like ordinary paper without the need for a backlight. Among the first commercial e-readers were Sony's Data Discman (which was using Mini CDs with special caddies) and the Rocket eBook. Several others were introduced around 1998, but did not gain widespread acceptance. Electronic paper was incorporated first into the Sony Librie that was released in 2004 and Sony Reader in 2006, followed by the Amazon Kindle, a device which, upon its release in 2007, sold out within five and a half hours. The Kindle includes access to the Kindle Store for e-book sales and delivery.
As of 2009, new marketing models for e-books were being developed and a new generation of reading hardware was produced. E-books (as opposed to e-readers) had yet to achieve global distribution. In the United States, as of September 2009, the Amazon Kindle model and Sony's PRS-500 were the dominant e-reading devices. By March 2010, some reported that the Barnes & Noble Nook may have been selling more units than the Kindle in the US. The Ectaco jetBook Color was the first color e-reader on the market, but its muted colors were criticized. As of 2021, a few color E-ink readers have been introduced into the market.Research released in March 2011 indicated that e-books and e-readers were more popular with the older generation than the younger generation in the UK.
