Advances that have transformed how the world communicates
Advances that transformed how the world communicates are among the top twenty-five technological breakthroughs of the past quarter century, according to a panel of experts assembled by CNN, June 19, 2005.
Advances in technology have done much to change the way we live and communicate over the past quarter century, but no breakthrough has revolutionized life as much as the advent of the "wireless world," according to a panel of experts assembled by CNN to pick the top 25.
In 1980, many telephones were attached to walls, facts were found in books, and people had to browse shelves in a record store if they wanted to buy the latest music. Now, access to all of those and more is found by just reaching into our pocket.
In the "Information Age" having immediate access to data is fundamental to progress. In some cases the advances are serving to overhaul industries at a lightning-fast pace.
The internet allowed tech-savvy music lovers to force changes in the way the music industry does business. Text messaging over cell phones has made written communication more immediate.
Having a computer in almost every American home (No. 5) has changed the way the world conducts business and how people communicate. Computers have gone from whirring behemoths to devices that fit in every room—or every pocket.
Just as computer use is exploding worldwide, the brains behind them—the processors—are getting smaller. Computer chips made the list at No. 9, and today a chip that you can balance on your fingertip can hold massive amounts of data.
This ability to store (No. 10) tons of information in cell phones or digital cameras allows us to keep our smart technology portable.
Even as our technology is getting faster and smarter, so is the e-baggage (No. 20) that comes with it.
When the internet age dawned, the World Wide Web seemed to be harmless. Today, however, we are mired in problems caused by things like online scams and viruses—traps aimed at taking down our computers and sometimes even our identities.
An entire industry meant to curb e-baggage and protect consumers has formed in reaction to this threat.
Scripting our entertainment experience
Technological advances have also transformed the entertainment industry.
Satellite television and radio (No. 13) give consumers more choices. The development of the remote control (No. 21) allows viewers to tailor their own experiences.
Video game technology has made great strides. In the early 1980s, the first wave of video games' popularity was in full swing with a little yellow Pac Man gobbling dots on a computer screen.
Today, the $10 billion a year industry produces realistic games that invite players into fantasy worlds, sports, and even wars.
The hunger for bigger and better screens with which to watch the tailored programs or new video games is being met with technological improvements. Advancements made to our television and movie screens—such as plasma TV, HDTV and IMAX—made the list at No. 24.
Leapfrogging into the future
Many life-altering innovations in the past quarter-century were made in scientific laboratories. Researchers decoded the genetic makeup of many organisms (No. 7), which led to advances in biotechnology (No. 4)—the science of manipulating an organism's genetic material.
DNA testing and forensic science (No. 14) made it possible to reunite an unidentified baby with his parents after the Asian tsunami. Law enforcement officers said it helped them crack the 30-year-old BTK serial killer case.
Amazing new technologies are changing the way crimes are investigated and solved, although this science is still not as immediate as many prime-time crime television shows make it appear.
Biometrics, the science of digitizing information; such as, fingerprints or facial features for accurate identification, and animal cloning join the ranks at Nos. 16 and 22, respectively.
Higher fuel prices sparked more interest in alternative fuel vehicles (No. 3), and so far hybrid vehicles curry the most favor with the growing number of consumers willing to pay more for their cars to save money on fuel. Hybrid vehicles are those that use at least two power sources, typically gasoline and electricity from batteries.
As low-tech as it may seem, the compact fluorescent light bulb is doing a great deal to revolutionize quality of life. It is one of the most successful energy and water conservation devices developed to date; others include low-flow toilets and showerheads. Together they rank No. 17.
In manufacturing, robots build some things faster and cheaper than human hands. Technologies; such as, computer aided design and computer aided manufacturing make it possible for someone to build prototypes of devices or parts using a mouse and a keyboard. These advancements make the list at No. 23.
At No. 12, advances in fiber optics—very thin strands of glass that transmit light and data much more efficiently than wires and cables—not only improved the quality of voices transmitted over phone lines but also made high-volume phone traffic possible.
From banking to shopping to investing, technology and the Internet are transforming the way we conduct our global banking and financing, and our experts ranked this shift at No. 8 on the list.
Breakthroughs in defense technology (No. 2) changed the face of warfare. Smart bombs are guided to their targets by satellites. Robots are used to disarm roadside bombs in Iraq and to search out caves in Afghanistan.
Although laser technology (No. 6) was patented in 1960, it took years before it found practical applications in medicine and CD and DVD recording and playback.
In space exploration (No. 11), the Hubble telescope has allowed us to peer into galaxies more than 12 billion years away. Unmanned spacecraft have landed on Mars.
Rounding out the top 25 are advances storage batteries (No. 19), weather prediction (No. 25) and the development of microscopes called STMs—scanning tunneling microscopes (No. 18)—that allow scientists to see minuscule images; such as, a fly's face in 3-D.
