As I commented when this came up yesterday, there are older (and better!) examples of a sharing economy. The Negro Motorist Green Book was a guidebook published 1936–1966 for African-Americans to have safe road trips during the Jim Crow era. Some of the information was voluntarily collected by U.S postal workers who gathered the information while on their routes. I say 'better' because paid couriers existed long before DHL. What DHL did (according to this account) was find a way to replace them with cheaper workers and not have to share the profits but instead use those profits to defend legal challenges against their business model.
