sectorul IT&C a contribuit la 16% din creșterea PIB-ului mondial (2002-2007)
în același interval, sectorul IT&C a crescut de la 5.8% la 7.3% din PIB
se estimează o creștere a sectorului IT&Cde până la 8.7% din PIB până în 2020

în lumea a treia, o creștere de 10 telefoane mobile la 100 locuitori a
stimulat o creștere PIB de 0.59%
în India, telefoanele mobile au generat o creștere cu 8% a profiturilor pescarilor, și o scădere a prețurilor la
bunurile de consum cu 4%
