1. Flats turned into mini hotels - existed since first highrise appartments started appearing in 3rd world countries
2. Carpooling - old as the world. In smaller Russian cities, people absolutely don't mind driving strangers around for a symbolic sum. In "good ol times" people used to do it for free.
3. Food devilery - phone order pizzas anyone? I remember first internet groceries started at around 1998, and they catered to really rich demographic living in far off suburbs ($30 just for the delivery fee, a daily income of a well off family back in 1998), but later internet only ones started to be displaced by existing grocery chains
4. "Microcommerce" - I don't know why Americans classify just selling anything with an app as such and why it is anything special
5. Regional same day delivery couriers - same story
6. Alibaba thing - classifieds in a newspaper?
All what Americans call the "sharing economy" or "economy 2.0" was what 80% of small business was about outside of the "developed countries"
