Crescono vertiginosamente i dati sull'utilizzo di Internet: in 60 secondi, nel mondo, vengono scambiate 187 milioni di email, 38 milioni di messaggi Whatsapp, 18 milioni di sms. Si scaricano 375'000 app e si spendono quasi 900'000 dollari in e-commerce. Un traffico che ogni giorno genera circa 3 quintilioni di byte (una cifra a 18 zeri). Mentre nel mondo le persone connesse alla rete hanno toccato quota 4 miliardi.
A fare i conti di questa attività online è Cefriel, la società italiana partecipata da università, imprese e pubbliche amministrazioni. "Negli ultimi due-tre anni è stato creato quasi il 90% dei dati disponibili ad oggi. La corretta analisi dei Big Data porterà alla creazione di nuove professioni che dovranno raccogliere, catalogare e tradurre in opportunità di business" questa grande mole di dati.
Nel calcolo di Cefriel su cosa accade ogni minuto online, rientrano anche i video di Snapchat (2,4 milioni), i login su Facebook (arrivano a 973'000), mentre i tweet inviati sono 481'000 e gli scroll su Instagram arrivano fino a 174'000m.
