Daylight Saving Time as we know it today has been heavily influenced by companies that live in urban settings not agriculture, as you may have misheard. Contrary to common belief, farmers did not lobby for daylight saving time and even fought against it in 1919.
However, they lost against urban retail outlets, such as fast food and tourist companies, who were in favor of the time change. In 2007, after lobbying for decades, companies that craft sweets gained victory with a change that moved Daylight Saving to after Halloween.
