Yahoo! begins advertising its web-based search service on national television, featuring the tag line “Do You Yahoo?”. The ads first air during Late Night with David Letterman, Saturday Night Live, and Star Trek. This was a very early example of the Internet entering into the mainstream.

The crew of the Space Shuttle Discovery deploys the US$2.5 billion Hubble Space Telescope. There will be initial difficulties caused by a flaw in the design of the telescopes mirror. Image correction software will keep the telescope useful until corrective optics are installed on December 25, 1993.

The Apple IIc was Apple’s first attempt at a portable computer. Dealers place orders for more than 52,000 units on the first day. Apple also announces that over 60,000 Macs have been sold since their introduction in January that year. In contrast, the Apple III line only sold an estimated 120,000 units in the four years since it was introduced, losing Apple about $60 million dollars.

Version 1.0 of the web browser Mosaic is released by the National Center for Supercomputing Applications. It’s the first software to provide a graphical user interface for the emerging World Wide Web, including the ability to display inline graphics. The lead Mosaic developer is Marc Andreesen, one of the future founders of Netscape.
My first experience with the World Wide Web was in 1993 using Mosaic on a Mac in my dorm’s computer lab. I had no idea what I had discovered until a few months later.

The Tandy Corporation holds a press conference to announce plans to build clones of IBM’s PS/2 system computers. The conference comes soon after IBM’s announcement that it would license patents on key PC technologies. IBM made this decision as they realized they were losing control of the “IBM-compatible” PC market and could make more money licensing the technologies. Within five years, IBM clones will become more popular than the original IBM machines themselves. Eventually IBM would leave the PC manufacturing business altogether, selling their PC division to Lenovo in 2005.

During the COMDEX Spring ’98 and Windows World shows in Chicago, a public demonstration of the soon-to-be released Windows 98 goes awry when Bill Gates’ assistant causes the operating system to crash after plugging in a scanner. Instead of showing the plug-and-play capabilities they were trying to demonstrate, a “Blue Screen of Death” is visible by the entire audience which immediately erupts in laughter. After several seconds, Bill Gates famously responded, “That must be why we’re not shipping Windows 98 yet.”
Ironically, the assistant, Chris Capossela, has moved up the executive ranks at Microsoft, recently being promoted to the position of Senior Vice President, Consumer Channels and Central Marketing Group. For Microsoft’s sake, hopefully he’ll present a much better marketing image then he did that fateful day!

Electronics magazine publishes an article by Gordon Moore, head of research and development for Fairchild Semiconductor and future co-founder of Intel, on the future of semiconductor components. In the article, Moore predicts that transistor density on integrated circuits will double every eighteen months for “at least” the next ten years. This theory will eventually come to be known as Moore’s law and it still holds true to this day. It is predicted that Moore’s Law will continue to be valid through 2020 or later.

The Osborne Computer Corporation officially announced the Osborne Executive portable computer, the follow-up to its extremely successful Osborne 1. This is the computer that according to lore, took down the company. Known as the Osborne Effect, the legend is that by leaking the announcement of this computer earlier in the year, dealers cancelled all orders for the Osborne 1, effectively destroying the company’s cashflow and hindering operations going forward. This resulted in the cancellation of the company’s IPO and eventually to bankruptcy.
The reality may not be so simple, but my research shows that the Osborne Effect may have been a contributing cause to the company’s demise, along with the rise of competitors, the introduction of the IBM PC, and mismanagement by the company’s president, brought in by investors to provide “adult supervision”.

The spacecraft Surveyor 3 is launched from Cape Kennedy, Florida. It is the second U.S. spacecraft to make a soft landing on the Moon (Surveyor 2 crash landed) where it will study the lunar surface and send more than 6,300 pictures back to Earth. In all, seven Surveyors will be sent to the Moon, five of them successfully completing soft landings.
