The diagram below gives information about the number of parcels delivered by two major mail services companies from 1920 to 2000.

The graph shows how many parcels were delivered by two main companies ,namely TNT and

Fedex

between 1920 and 2000.

Overall

,

it is clear that

there were considerable increases in the number of parcels delivered by both companies .

Additionally

, it is

also

worth mentioning that TNT was the largest sector and the

figure

overtook that of

FedEx

at the end

,despite being the smallest point at the beginning.

Initially

, in 1920,

FedEx

was the most dominant mail company in delivering parcels with 15.000. After rising sharply to 20.000 during the first 20 years,the

figure

fell briefly to around 12,500 in 1950.The

figure

,

however

, started to improve again with slight fluctuations and had reached well below 20.000 by the

last

year. Turning to the latter, the

figure

was quite opposite to the tendency of the

Fedex

company .The

figure

for TNT stood out as the smallest sector ,

on the other hand

, accounted for 5.000 in the first year

then

quintupled

at the end

of the period before remaining stable at approximately 11.000 between 1960 and 1980.
