How often do you order delivery for a meal? According to data from research firm NPD Group Inc. and the U.S. Department of Agriculture, around 82 percent of meals were prepared at home last year, which is up by two percent from a decade ago. But there has also been a huge increase in people getting food delivered for meals. Now, you can get food from just about any type of restaurant and thanks to services like Grubhub, Seamless and Caviar, as well as online ordering systems, it’s an option that’s spreading to all parts of the country. Host Dan Loney talks with Heather Haddon, Food and Retail Policy Reporter for The Wall Street Journal, to discuss her reporting on this shifting food delivery industry on Knowledge at Wharton.
