Conventional wisdom states that body text benefits most from being set in a serif font because the serifs create a path for the eye to follow along a line and down to the next.
Despite that, many web designers have for a number of years, argued for the use of sans-serifs; and with good reason: the addition of serifs to a letterform on a screen quite literally blurs the word shapes, reducing contrast and readability.
Numerous studies have been conducted on the matter and the conclusion that most arrive at is that readers prefer whichever style of type they are most familiar with. Consequently, it would seem that either option is fine, provided it is familiar to your visitors.
However, there is a style of type that produces the strong horizontal bars of text that serifs excel at, whilst still enjoying the high contrast of sans-serifs: the Egyptian, or slab-serif.
To understand why slab-serifs are perfect for the web in 2013, you need to understand where this style of type came from.
Slab-serifs (originally called Egyptians) first became popular in the wake of Napolean's Egyptian campaign (1801) and coincided with the beginning of the industrial revolution. More specifically they evolved in line with Koenig & Bauer's updated printing press that revised Gutenberg's centuries-old design; purchased by The Times in London, the new printing press made newspapers accessible to the mass population for the first time.
Almost exactly 100 years later, slab-serifs experienced somewhat of a renaissance, as discoveries such as the unearthing of Tutankhamun's tomb in 1922, coincided with the explosion of advertising between the wars. The fashion for Egypt, and the solid characteristics of slab-serifs ingrained the style in the public consciousness.
In both cases, the fashion for slab-serifs was only able to grow because the letter forms function so well on cheap paper, and under low-quality printing conditions.
The same characteristics that make slab-serifs so robust, and ideal for low-quality print work, also make them ideal for the web.
In a world of retina displays, we often forget that the web is still very much a place of pixels. Whilst some devices are certainly capable of outputting beautifully rendered pages, any web designer worth their salt will be aware of the commonality for poorer quality displays.
Slab-serifs are a high-contrast, horizontally biased style of type that are not only highly legible, they also produce well-defined lines of text, reinforcing the baseline grid.
Many fonts we choose for the web were designed for print and take into account ink spread; with no ink spread on the web, fonts become too light and lose much of their detail. Slab-serifs, by comparison, tend to be far heavier and consequently retain much of their character when rendered in pixels.
The biggest benefit of slab serifs is the high-contrast between the type and page, produced by the minimal contrast between the stroke and serifs, and (usually) the lack of brackets.
