It was common as far back as the 1910s for newspapers to put out "Week-End Supplements," which were usually rotogravure sections featuring the most impressive news photos of the week just drawing to a close. These eventually evolved into the fancy "Coloroto" magazine sections of later decades, and then devolved into the chintzy little "Parade" type supplements that linger on today. While a few workplaces introduced the five-day week around the turn of the century, until the mid-1930s the six-day week was the norm for most working Americans. Most offices and nearly all factories were open for a half-day on Saturdays. The five-day 40-hour work week, long a goal of organized labor, was a pillar of many of the industrial codes imposed by the National Recovery Administration, and that led, eventually, to its institutionalization under the Fair Labor Practices act of 1938. That was the beginning of the modern concept of the "weekend."
