Understanding Information Consumption Trends in the U.S. (2009 Study)

This 2009 study by Roger E. Bohn and James E. Short, presented by Eun-Sol Kim, explores how much information Americans consume daily. On average, Americans receive 11.8 hours of information each day, translating to about 100,000 words. The study highlights the significant influence of television, computers, radio, and smartphones on information consumption. It also notes a rapidly growing trend in digital media and an increase in data consumption rates, providing insights into the evolution of media usage and future implications for information dissemination.

  1. How Much Information? 2009 Roger E. Bohn James E. Short Presented by Eun-Sol Kim

  2. 1. Introduction - notation

  3. 1. Introduction – the scope of the information

  4. 1.3 How many hours? INFOH : hours spent receiving information How much time Americans spend with different sources of information. An average American on an average day receives 11.8 hours of information a day.

  5. 1.4 How many words? • 4,500 trillion words consumed in 1980 (Pool) • 10,845 trillion words consumed in 2008 • 100,000 words per American per day

  6. 1.5 How many bytes? • Moving pictures dominate all other types of consumer information. • Only three activities contribute a significant amount of information based on INFOC : • TV, Computer games, Movies in theaters • 34 gigabytes (3.4*10^10 bytes) per day in 2008, • 34 gigabytes = 7 DVD disks = 1.5 Blu-ray disks

  7. 1.5 How many bytes?

  8. 1.6 Storage vs. Consumption • This paper measured data as information each time consumers use it. • Stored data is not necessarily information. • The data ‘footprint’ of a storage device is not just how many bytes it holds, but how many bytes are created over time.

  9. 2. Traditional information in U.S. households • Information • In households and mobile uses • Information for consumption • In workplaces and between machines • Information for production

  10. 2.1 Television • TV is the largest source. • TV usage measured in hours per person is rising only slowly.

  11. 2.2 Radio • Thriving on new technology • HD audio, satellite transmission, online radio.. • But audio requires very low data rates in census. • HDTV requires 30 times more than audio. • 233 million radio listeners • 10 exabytes of information in 2008

  12. 2.3 Telephone • 143 million wired lines in 2008 • 263 million wireless users • Average wired lines : twice as many minutes per day • > information words are slightly higher for fixed lines. • Total time consuming information • Wire : wireless = 3.2 percent : 2.9 percent • 1 household uses home phone for 22.5 hours each month • Total voice traffic by wired phone in 2008: 1.2 exabytes • Total voice traffic with wire and wireless : 1.4 exabytes

  13. 2.4 Print • 5% in INFOH, 9% in INFOW, 0.02% in INFOC • E-book have already taken over for paper

  14. 3. Computer information in U.S. households • 10 years ago • 40% had a PC, 24% had Internet access • Now • 70% had a PC with Internet access • 80% with smartphone devices • One households has dozens of digital devices for entertainment, information and so on. • 3G phones, PDAs, MP3 players, TV, PC, game devices….

  15. 3.1 Communicating and browsing the internet • In 1980s • No email, fax • Today • 220 million Americans spend 14% of their INFOH on the internet • Email : the most widely used application (35%) • Americans spent fewer hours on web browsing ( 30% of the Internet time) • Most users spend 8-9 seconds looking at most web pages. • Find the page of interest, change their minds, get bored/shift to another task.

  16. 3.2 Internet video • This article measured internet video such as YouTube • 95 million viewers • Average viewing time : less than 2 hours per months • Internet video is still small • INFOH : 0.2% of the total • INFOC : under 1 exabyte • Because the speed of the pope into the house limits how much can be received while the consumer is actively trying to watch.

  17. 3.3 Computer Gaming • Computer gaming has come to dominate the total number of information bytes : nearly 2 zettabytes in 2008 (55%) • Total of consuming hours less than 8% • Total of consuming words about 2.5 % • 70% of adults played computer games, less than one hour a day

  18. 3.4 Off-internet home computer use3.5 Smart phones • Off-line use • Updating a resume, editing photos, running a household finance program • Only 17 minutes per day per average American. • Almost text based, 0.7 exabytes per year • Smart phones • In 2008, 263 millions American carry cell phones • 50 millions American carry smartphones • American spent 7 billion hours text messaging

  19. 4. Trends, Perspectives and the future of U.S. information consumption 4.1 Analyzing the growth of information • In INFOC point of view • 5-fold increase from 1980 to 2008 • Annual growth rate : 5.4% • cf ) the Moore’s Law • Three components of the information consumption • Population : grew at 0.95% per year • Average hours per person spent consuming info : grew at 1.7% per year ( 7.4 h to 11.8 h ) • Average information per hour • Average bandwidth ( information intensity ): grew at 2.8 % per year ( 2.9 Mbps to 6.4 Mbps ) • Gigabytes per person per day : grew at 4.4 %

  20. 4.2 Where are the missing bytes?

  21. 4.3 Analyzing information consumption

  22. 4.4 The future of consumer information • The most visible is shifts in TV • To digital broadcasting, the mass acceptance of high definition TV sets, digital video recorders • Mobile TV, video over the internet • Computer games
