A Netbook is a category of computer that are light-weight, small in size and are legacy-free. In terms of features, it comes with a small screen and keyboard minus the optical drive. It is smaller than a full-sized laptop. Over the period of time, since their inception, they have evolved to be smaller with a screen diagonal of 5" to 12" and with a weight of around 1kg. They are cheaper than laptops. Toshiba was the first company to come up with a Netbook in 1996. It weighed around 840g. It was called the "Libretto sub-notebooks".The Asus Eee OC 700 model was the first Netbook that was produced on a mass scale.It came with a 7 inch screen.
By 2011, the sales of Netbook started to decline rapidly because of Tablet Computers like the iPad, which came with better computing capabilities and lower cost of production. To improve the Netbook market, companies like Apple came up with MacBook Air, which were ultra light. Later Intel came up with Ultra Book which covered most of the areas where Netbook failed. Thus, in 2011, with these two developments, the notebook was left only with a lower price as their strong point, losing in the portability department, design and ease-of-use to Ultrabook and Tablets. By the end of 2012, all the companies stopped producing Netbook.
