First, a curmudgeon's view of the Internet.
Statler and Waldorf are named for the famous hotels in New York. Believe it or not they have their own Wikipedia page. They also had their own show called From the Balcony. |

OK, some history. In the beginning, there was the telegraph... --- ... Samuel Morse's invention was soon powerful enough to span the Atlantic ocean. When it did, technicians noticed that the telegraph cables attracted metal objects like a magnet. Meanwhile, Thomas Edison, inventor of the telegraph, phonograph,
electric light and other things, noticed This was the beginning of electronics, of radio and TV, and of computing. |

Charles Babbage 1791-1871 / 1833 design for a difference engine // Eccentric, English mathematician who is considered to have conceptualized the modern computer a century before technology let it be built. He conceptualized the Difference Engine, a machine that would have computed lengthy scientific tables, but money, labor, and health problems prevented its completion. The Analytical Engine, a more ambitious plan, would have done a wide range of calculating tasks. With it, Babbage recognized the need for an input device, memory, a central processing unit, and an output device, and for this he is known as the Father of Computing. (Important people...) |

Alan Turing 1912 1954 British cryptographer, computer
designer, artificial intelligence English mathematician who was crucial in the work at Bletchley Park designing the Colossus, which deciphered German code during WWII and is considered to be the first electronic computer. He later invented the Turing Test, in which he proposed that if a computer could pass his test, it had proven that it could think. (So far no computer has passed). |

Grace Hopper 1906 - 1992 American computer specialist with US Navy, developed COBOL language / naval research The famous quotation "It's easier to ask forgiveness than it is to get permission" is often attributed to Grace Hopper.[8]Also attributed to her is the quote, "A ship in a harbor is safe, but that is not what a ship is built for." |

Although they were developed for the radio industry, the vacuum tube allowed machines to calculate several times faster than adding machines. This IBM tube system from 1946 could multiply two 10-digit numbers 40 times a second. |
|||
The tubes were used in a machine called the ENIAC -- Electronic Numerical Integrator And Computer. It was designed and built to calculate artillery firing tables for the U.S. Army's Ballistics Research Laboratory and was used to calculate problems for H-bomb development. According to Wikipedia and other sources ENIAC:

Yet connecting these 10,000 transistor is very difficult, and there is bound to be a flaw somewhere. |

THE CHIP |

|
|
Engineers soon realized there was no need for transistors to be separate. In fact, the idea of the integrated chip occurred at the same time to a number of people. In 1958 Jack Kilby of Texas Instruments (left) used a germanium slab and interconnecting wires. The following year, Bob Noyce of Fairchild Semiconductor developed a silicon circuit with deposited metal lines -- ideally suited for mass production, and containing the three basic elements still found in chips today (a layer of transistors and an interconnection layer, separated by an insulating layer). Noyce and Gordon Moore founded Intel in 1968. | |||

Computing power doubles every 12 - 18 months. (From Whatis.com) The pace of microchip technology change is such that the amount of data storage that a microchip can hold doubles every year or at least every 18 months. In 1965 when preparing a talk, Gordon Moore noticed that up to that time computer processing capacity seemed to double each year. It still does. |
|
|||
Around this time, people started taking notice of computers. Here's a 1969 BBC program that gives a fair idea of how computers were changing life even then, and how people reacted to computers. |
||||
| 1971 First microprocessor, the 4004, developed by Marcian E. Hoff for Intel, was released. It contains the equivalent of 2300 transistors and was a 4 bit processor. It is capable of around 60,000 Interactions per second (0.06 MIPs), running at a clock rate of 108KHz. | ||||
Many people were worried that computers could be used by governments to dominate and tyranize by organizing confidential information about them. So this theme of computer liberation, first promoted by Ted Nelson, ran throughout the industry. |

The Apple Mac computer was developed as part of this anti-1984 theme. Understand that the PERSONAL computer was one that the government couldn't watch you use. What people really feared was the networked computer with dumb terminals, where everything ran through a central computer. This view, possibly antiquated, may stand in the way of developing networked applications on a broad scale. |

Computer power kept increasing ... |
1978 Introduction of 8086 by Intel, the first commercially successful 16 bit processor.An 8 bit version was developed (the 8088), which was chosen by IBM for the first IBM PC. The 8 MHz version achieved 0.8 MIPs and contained 29,000 transistors. 1983 -- 12.5 MHz, achieved 2.7 MIPs and contained 134,000 transistors 1989 -- 80486 DX released by Intel. It contains the equivalent of about 1.2 million transistors. At the time of release the fastest version ran at 25 MHz and achieved up to 20 MIPs. Rising computer power means consumers can do far more with less. Standard consumer computers, by around 2005, ran at 2,000 MHz (See How do microprocessors work?) 2007 -- IBM's BlueGene/L - 280.6 TFlop/s “teraflops” or trillions of calculations per second or 140 million times faster than the 80486 |

The three cultures of computing in the 1970s and 80s ... |

Ironically, just as IBM was being sued by the Justice Department over its business dominating tactics, the company missed the "curve in the road" and lost its core software business to the nerd engineers. |
||||
Nerd engineers like Bill Gates, founder of Microsoft, opened up the capabilities of personal computing. Gates developed an operating system for IBM but held onto the copyright. IBM thought that the hardware would be the key to the future of the business. Gates predicted that software would be the key. He was right. |
||||
Hip visionaries like Steve Jobs, founder of Apple, wanted to develop "insanely great" technologies. With the help of Steve Wozniak Apple became the first big personal computer company but had a hard time breaking into the business market. |

Xerox and IBM miss
the "curve in the road" 1970s
- 80sNerds and Hips came together to develop 3 key technologies
- GUI and mouse
- networking thru ethernet
- Object oriented programming
"Killer" applications 1970s
- 80sSolutions in search of a problem
Steve Jobs · Steve Wozniak Apple II / first PC sells for $1,195 in 1977
Bill Gate, Paul Allen, create DOS, control software not hardware
Visicalc spreadsheet first killer Ap for PC / Apple
IBM's blessing in 1982 opened up markets but most bought reverse engineered "clones" -- but everyone had to buy DOS
Apple Mac = second killer ap for wysiwyg = Desktop Publishing
Third killer ap = email / web
Where did the Web
come from? 1960s
- 80sNetworking
1968 -- DARPA (part of the Dept. of Defense) began networking its computers in 1969 as part of the space race. There was resistance -- computer time was precious. So much so that people starting thinking the unthinkable -- personal computers.

1982 Viewtron and Gateway debut, flop by 1985
1988 Prodigy by Sears (CBS bows out)
1990 First Prodigy experiments with news sites, very clunky
1994 First news Web page San Jose Mercury News
1995 MSNBC formed; most new organizations now have Web sites
1996 -- Telecommunications Act
1997 -- Reno v. ACLU meant regulation of internet and web was to be like print not like broadcasting. (No Federal Internet Bureau).
21st
CenturyWEB 2
2001 -- Napster lawsuit spawns P2P software development, lawsuits agains Grokster and others...
2003 -- Apple recovers from its long dark tea-time of the soul with i-Pod
2005 -- New media technologies emerge within the overall framework of the web. Basic links for student research projects at Radford University include:
- Podcasting
- Blogs
- RSS feeds
- Collaborative working spaces (YouTube, Flicker, Wikis and others)
- Mapping technologies
