Nov 22nd 1977 - first time Arpanet, radio and satellite networks all communicated together.
1997 50 million users, today 1114 million users. =argest is Asia with 398.7 mill. Africa has 33.3 million and greatest potential for expansion.
Vint Cerf was the person who decided in 1976 that 32 bits was fine for address space for the purpose of the experiment they din't know would work. These will run out in 2011. IPv6 should solve this.
Socio-economic effects of internet:
Consumers are now producers. The barrier to contributing has dropped to 0.
Social Networking - people organising the web around themselves and their friends
Gameplaying in Second Life and WoW etc
New business models such as eBay and Amazon that are not possible without internet.
Internet can transport and display print, video, audio media
Internet permits group interaction (not only mass one-way medium)
Cerf bought 10 million bits of storage in 1979, and was very excited about it. Cerf bought a terrabyte recently for 1000 dollars. He calculated a terrabyte would have cost 100 million dollars.
Arpanet backbone ran at 50 KB per second, now internet backbone is gigabits per second.
Discusses possibility of downloading ancillary information with video, captions, audio, etc. You could pause video then click object or parts of the video to get more information. You could have adverts based on user location - pause a cooking show, click on the bottle of wine and get information on where to buy it nearby.
Mobiles are not just telephones anymore. Text can be used to control entertainment systems or for payment systems (especially in places whre people don't have bank accounts but have mobiles). Tiny screens (suitable if you're three inches tall :-) but are now often have navigation systems inside. Queries are now in real-time. We can do google queries when we need to and don't have to plan beforehand.
We can't print copies as backup anymore as information is often 3d interactive objects. Now we need to worry about "Bit Rot". Preserving interpretive programs (trying to use Powerpoint 1997 on Windows 3000) and the operating system, and hardware that runs the OS, for thousands of years. In a thousand years information that might have been useful we might not have access to.
Billions of devices on the internet soon. One guy has created an internet enabled surfboard so he doesn't get bored waiting for the next wave.
InterPlaNetary Internet (Cerf working with NASA). We have rovers landing on Mars sending information back. They want to standardise the devices in deep space so that devices can pass information between each other. Rovers on Mars passed info to Mars satellites then onto Earth. "The distance between the planets is literally astronomical"
TCP IP doesn't work with a 45 minute delay and when the planets turn around inconveniently. A new protocol being developed.
Innovation happens when people can experiment without needing permission to try things. Google engineers get 20 percent innovation time. Opportunity to try things out without having anyone interfere. They share details so everyone is free to contribute. (note - do we allow kids to innovate in this way?!)
Bob Metcalf predicted in 1997 that the internet would have a 'gigalapse' and collapse. When it didn't happen he took the editorial he wrote, put them in a blender and ate them!
When asked about video being restricted to particular countries, Cerf believes internet should be a global communications medium. There needs to be inter-government cooperation to deal with problems of fraud etc.
