The line graph elucidates the trends in parcel deliveries by two prominent mail services, Federal Express and TNT Mail Services, from 1920 to 2000.
In summary, Federal Express consistently outperformed TNT in parcel deliveries throughout the majority of the observed period, although TNT exhibited substantial growth in the latter years.
Commencing in 1920, Federal Express recorded an initial delivery volume of zero parcels. The company demonstrated a progressive upward trajectory, achieving approximately 5,000 parcels by 1940 and further increasing to around 10,000 by 1970. A significant surge occurred in 1985, where deliveries peaked at approximately 25,000 parcels. However, this was followed by a minor decline to about 20,000 parcels in 1990, subsequently rebounding to an impressive total of 30,000 parcels by the conclusion of the period in 2000.
Conversely, TNT Mail Services also began its journey in 1920 with no deliveries. Its growth path was relatively gradual, reaching around 5,000 parcels by 1960. The subsequent decade witnessed a sharp escalation, propelling deliveries to approximately 15,000 by 1970. A decline to 10,000 parcels was noted in 1985, yet from 1980 onwards, TNT experienced exponential growth, culminating in nearly 27,000 parcels delivered by 2000, thereby reflecting a noteworthy upward trend that brought it closer to Federal Express.
