The line graph illustrates how many parcels were transported by two important mail services companies (Federal Express and TNT Mail Services) over the 80 years between 1920 and 2000.
Overall, it is noticeable that the number of parcels delivered by FedEx decreased rapidly at the beginning of the period, whereas the number of parcels delivered by TNT increased sharply and ranked first by the end of the period.
The quantity of parcels dispatched by Federal Express stood at 15000 in 1920. Then, the figure rose significantly to a peak of approximately 24000 parcels by 1940. However, between 1940 and 1960, it fell dramatically. In the following decades, Federal Express saw a noticeable rise, reaching about 18000 parcels delivered. By 2000, this made it the second-largest mail services provider.
In contrast, the number of parcels delivered by TNT Mail Services was approximately 5000 in the year 1920. This figure increased substantially over the period and hit a high of around 25000 transported parcels in 2000. By the end of the timeframe, TNT had become the most significant mail services provider.
