Forecasting the growth of the Internet Michael Minges, Telecommunication Development Bureau (BDT), International Telecommunication Union (ITU) Market Forecasting in the Telecoms Industry, 25-27 May 1998, Hongkong
Why is Internet forecasting important? Global phenomenon Growing market Revenue potential Compound Annual Growth Rate 1990-97 Source: ITU. …the most promising new economic opportunity in decades. Bill Clinton
What Internet numbers are important? Network size Traffic Market value
Network size Host computers Physical connections Subscribers Paying customers Users People accessing 267400 Subscribers 57600 Hosts 1.9% 500000 Users Source: TAS, Nielsen, Network Wizards. Singapore Internet Profile 1997 8.6% Percent of population 16.1%
Internet hosts Tight definition (IP address) Scientific method Regular surveys: Network Wizards Twice a year counts of all hosts RIPE Monthly counts of European hosts Marks minimum size of Internet Internet hosts, world Source: ITU adapted from Network Wizards. 5.07 29.7m 0.06 0.313m
Hosts: How reliable? Network Wizards January 1998 methodology change Differences between Network Wizards and RIPE Where do hosts actually reside (e.g.,.COM)? Internet hosts million Source: Network Wizards. 16322 32272 Trend Actual 1-95 7-971/98
Internet hosts: High growth over? Internet Hosts World, millions Internet Hosts Asia-Pacific, millions Source: Network Wizards.
Internet hosts: macro forecast Peak of highest growth Growth levels off Source: Dr. Mario Hilgemeier http://tunix.is-bremen.de/~mhi/inetgrow.htm Internet hosts millions S-Curve Trend High projection S-Curve error limit Source: ITU.
Internet hosts: Micro variables India China Indonesia Philippines Malaysia Thailand Japan Taiwan Korea Australia Hongkong Singapore Internet hosts per 1000 inhabitants GDP per capita India China Indonesia Philippines Thailand Malaysia Australia Korea Singapore Taiwan Hongkong Japan Telephone lines per 100 people Internet hosts per 1000 inhabitants Determinants of Internet penetration: Income Telephone lines PCs Age, education & language R2=0.45 R2=0.56
Internet users: How many online? 0 20 40 60 80 100 120 Jan-90Jan-92 Jan-94 Jan-96Jan-98 0 1 2 3 4 5 6 Users (m) Users per host Source: MIDS. Users per host Internet Users World, millions Source: NUA Surveys. Africa & Middle East 1% Canada & USA 59% Europe 20% Asia- Pacific 16% South America 6% Internet Users May 1998 119.5 million
Internet users: Guesswork? Loose definition makes estimating Internet users difficult Wide variation in estimates Previously multipliers, now surveys Internet Users Millions Source: ITU adapted from NUA Internet Surveys. There is no way to determine how many users are on the net, besides making guesses and estimates. Network Wizards
Users forecast Will grow faster than hosts Limited by various variables (number of PCs, telephone lines, etc.) Internet users World, million Source: ITU, MIDS.
