Final answer:
The reference provides information on how a change in consumer preferences from traditional mail to digital communication affects demand for the Postal Service. While it doesn't detail the first step in changing a postmaster address, it outlines the economic impact of changing consumer trends on service demand.
Step-by-step explanation:
The first step to change the postmaster address is not explicitly stated in the provided information. However, the provided reference discusses the economic concept of how a change in consumer tastes can affect the demand for a service.
In this case, it explains that a shift in preferences from using traditional mail services (snail mail) to digital messaging platforms will result in a decrease in demand for Postal Service offerings.
This is because as more people prefer to use digital channels for communication, the number of customers seeking out postal services is likely to decrease, thereby reducing the demand.
This economic principle illustrates how changes in consumer behavior can have a significant impact on businesses and services, necessitating adaptation and evolution to meet shifting market conditions.
