The growth in the internet, 24-hour television and mobile phones means that we now receive five times as much information every day as we did in 1986. But that pales into insignificance compared with the growth in the amount of information we churn out through email, twitter, social networking sites and text messages. Every day the average person produces six newspapers worth of information compared with just two and a half pages 24 years ago – nearly a 200-fold increase. All this information needs storing and we now each have the equivalent of 600,000 books stored in computers, microchips and even the strip on the back of your credit card. The extent of the information revolution and digital age has been calculated by Dr Martin Hilbert and his team at the University of southern California. They used a complex formula to calculate the average amount of information stored – and sent – in the world – from every medium from computers to paper and books – to letters in the post. "These figures show that we are in the middle of the information age," Dr Hilbert said. "When you think that 100 years ago people were lucky to read the equivalent of 50 books in a lifetime but now most children have watched a couple of hundred movies. "But the brain is a very plastic and very good at understanding and processing information." The researchers surveyed 60 categories of analogue and digital technologies during the period from 1986 to 2007, and the results reflect our near complete transition to the digital age. Using the analogy of an 85 page newspaper, they found that in 1986 we received around 40 newspapers full of information every day but this had rocketed to 174 in 2007. In 1986 we sent out – mainly by post, telephone and fax – around two and a half pages of newspaper each day. This had increased to six newspapers thanks to email, digital photography, Twitter and social network sites by 2007. The actual switchover from analogue to digital occurred in 2002 and now 94 per cent of all data is stored in a digital form. Just 10 years ago – it was just a quarter, the vast majority still stored on video and audio cassettes. The world’s capacity for two-way telecommunication, such as internet and phone networks, grew by 28 per cent per year while one way information flows through television and radio grew at the much more modest rate of six per cent per year. The researchers, who reported their findings in the journal Science, found that there was now 295 exabytes of data floating around the world – that's 29,500,000,000,000,000,000,000 pieces of information. While this is enormous – 315 times the number of grains of sand on Earth – Dr Hilbert points out it is still less than one per cent of the information that is stored in the DNA of a single human being. The ability to process all this information with computers has doubled every 18 months and with telecommunication devices has doubled every two years. But despite it showing enormous growth, Dr Hilbert said we are far from saturation point and nowhere near dealing with the amount of information contended with in the natural world. Dr Martin Hilbert, of the University of California, said: "These numbers are impressive, but still minuscule compared to the order of magnitude at which nature handles information. "Compared to nature, we are but humble apprentices. If we tried to store the name of every star in the Universe we could only file one per cent."

Znate li da dnevno 'pročitate' 174 novine? Prije 100 godina ljudi bi bili sretni kad bi tijekom čitavog života pročitali 50 knjiga ili toliki ekvivalent informacija. Danas djeca bez problema pogledaju nekoliko stotina filmova Jeste li znali da svakog dana u prosjeku dođete u doticaj s količinom informacija ravnom onoj koja se nalazi u 174 novine? Drugim riječima, svakog dana pročitate 174 novine i to bombardiranje informacijama se nimalo ne smanjuje. Prema američkim istraživačima, na svijetu cirkulira oko 295 heksabajta podataka ili oko 295 milijardi gigabajta. Rast interneta, cjelodnevni televizijski programi i mobilni telefoni znače da danas primamo pet puta više informacija nego što je to bio slučaj 1986. godine. Prosječna osoba dnevno proizvede informacija koliko ih ima u šest dnevnih novina - prije 24 godine ta je količina bila dvije i pol stranice, gotovo 200-struko povećanje, prenosi časopis Znanost (Science). Sve te podatke treba negdje spremiti, a mi danas u običnom računalu, mikročipovima pa čak i na kreditnoj kartici imamo mjesta za 600.000 knjiga, piše Telegraph. Raspon informacijske revolucije i digitalnog doba izračunali su Martin Hilbert i njegov tim sa Sveučilišta Južna Karolina. Poslužili su se posebnom formulom kako bi izračunali prosječnu količinu informacija koja se dnevno pošalje i spremi preko svih postojećih medija - računala, knjiga i najobičnijih papirnatih pisama. „Brojke pokazuju da smo usred informacijskog doba", kazao je Hilbert. „Pomislite samo na to da su ljudi prije sto godina bili sretni ako su pročitali informacija koliko ih ima u 50 knjiga i to tijekom svojeg čitavog života, a današnja djeca pogledaju nekoliko stotina filmova bez ikakvih problema. Godine 1986. slali smo - uglavnom putem pošte, telefona i faksa - oko dvije i pol stranice novina informacija svaki dan. To se povećalo na šest čitavih novina na dan zahvaljujući e-mailu, digitalnoj fotografiji, Twitteru i ostalim društvenim mrežama do 2007. godine", kazao je Hilbert. Pravi prijelaz sa analognog na digitalno doba zbio se 2002. godine i danas je 94 posto svih podataka spremljeno upravo u digitalnom obliku. Istraživanje je, dakle, pokazalo da danas cirkulira oko 295 heksabajta podataka diljem svijeta - to je pak oko 29.500.000.000.000.000.000,000 informacija, tvrdi Hilbert u svojem izvješću (jedan heksabajt je jednak jednom kvintilijunu bajta ili jednoj milijardi gigabajta ili jednom milijunu terabajta)
