These pie charts show the contrast between the usages of the different means of communication –computer, letter and phone- in Someland between the years 1962 and 1992. As it can be clearly appreciated, these different means of communication have evolved differently during this period: electronic means as the computer and the phone have substantially increased their number of users whereas the usage of the letter has dramatically declined.
In 1962, 50% of the total population of Someland used the letter as their personal choice for communication processes, which converted the letter into the most important means of communication at that time. Nevertheless, during more recent times, as we can easily see in pie chart 2, the number of the inhabitants of Someland using the letter has sharply and rapidly dropped to 10%, becoming the less employed option of the possible three. On the other hand, very positive evolutions can be appreciated in the cases of both the phone and computer during the same period. Despite the fact that the phone was moderately used in 1962, with 35% of the population, it has steeply gained more users during this period, climbing to 60% of user in 1992, a percentage that converted it into the major means of communication used in Someland at that time. A similar tendency can be perceived in the case of the computer, - the online communication process-, the enormous and rapid upward of the number of computer users for communicative purposes in 1992 -30%-, specially if compared to that of 1962 -15%- clearly proves the great significance the online communication has achieved during recent times.
As a conclusion, it could be said that the significant differences in the evolution of the various means of communication prove the well-known tendency of the increase of the usage of technological means, such as the computer or the phone, rather than the most traditional ones
