Prof. Howard Weiss, retired from Temple U., shares his thoughts with our readers monthly.
The history of gasoline service stations provides an excellent illustration of life cycles as discussed in Chapter 5 of your Heizer/Render/Munson textbook
Before There Were Gas Stations The first practical gasoline-powered auto was developed in 1886 by Carl Benz. Prior to that, some inventors experimented with steam-powered vehicles, while others relied on kerosene because it was inexpensive, widely available, and burned efficiently. Early motorists purchased gasoline in bulk containers from pharmacies, blacksmith shops, or general stores and then poured the fuel into their vehicles using a funnel. Although this process seems inconvenient today, it was sufficient when automobiles were still a novelty.
Life Cycle Stage 1: Introduction
In 1905 the Automobile Gasoline Company opened the first gas station, in 
St. Louis. The station consisted of little more than a curbside pump with a hose, allowing motorists to fuel their vehicles directly instead of using portable containers. Gasoline sold for 25 cents a gallon. In 1913, the first drive-in service station opened in Pittsburgh, and also expanded the customer experience by offering free air, water, crankcase service, tire installation, and road maps.
Life Cycle Stage 2: Growth
During the growth stage, automobile ownership expanded rapidly, and so did the number of gasoline outlets. By the 1920s, major oil companies had standardized station designs and logos, creating recognizable national brands. Self-service fueling was introduced in the 1940s and became commonplace during the 1970s, reducing labor costs while increasing customer convenience. Today, many filling stations are combined with convenience stores such as Wawa, where merchandise sales often generate higher profits than gasoline itself.
Life Cycle Stages 3 & 4: Maturity and Decline
The number of gasoline outlets peaked at around 285,000 in 1975 and then entered a steady decline. Small independent stations found it increasingly difficult to compete with larger, multi-pump convenience stores that benefited from economies of scale and higher-margin retail sales. The number has been fairly constant at about 145,000 since 2000.
The growth of EV charging stations, beginning around 2007, interestingly, has not yet produced a corresponding decline in the number of gas stations. The future of gas stations will partially depend on the pace of EV adoption, but its history remains an excellent example that not all life cycles have the same shape.
Classroom Discussion Questions;
- What information would you want in order to forecast the number of gasoline outlets that will exist in 2040.
- Could linear regression be used to forecast the number of electric charging stations in 2040?
