The answering machine edges out the sewing machine. The electric guitar trumps the electric toothbrush. But from alarm clock to zipper, all of the items on our list have cultural signifi cance that belies their physical size. Ground rules: A gadget is something you can hold in your hands. Mechanical or electronic, it is a mass-produced, personal item that evolves from novelty to necessity and ultimately shows its paradigm- shifting power. All were selected and ranked by PM, HISTORY and a panel of esteemed inventors, designers and tech gurus, including a moon-walking astronaut. Let the countdown – and the inevitable debate – begin.
By the editor

1. Mobile/ Smartphones

The judges argued over all but one ranking: the smartphone was an easy top pick. With origins tracing back to Finland and Japan in the ‘70s, mobile phones have fast become the most widely used gadgets in the world. The first billion units sold in 20 years, the second billion in four years and the third billion in two. By the end of 2010, the subscription rate stood at 5 billion, or 3 of every 4 people on Earth. The tech leapt forward in 1983 with the Motorola DynaTAC 8000X, the first truly portable cellphone. The smartphone, with us since 2000, is now a pocket-sized PC. Wireless and GPS- and multimedia-enabled, it facilitates instantaneous personal connections that make phone conversations seem like cave paintings. People of developing nations, even those without an electrical grid, can tap into the world’s commerce and culture. After a scant 11 years of development, the device seems to have limitless potential.

2. Radio

Patented in 1896 as "wireless telegraphy" by Guglielmo Marconi – who based his work on technology developed by Nikola Tesla.

3. Television

Conceptualised in 1877 by Edison and Bell and patented by inventor Philo T Farnsworth in 1930, television spread rapidly after World War 2. Except in South Africa, that is, which got the goggle box only in 1975. Less than four decades later, SA was beaming the FIFA World Cup 2010 to billions worldwide.

4. Hypodermic Syringe

Invented in 1844, among other things it's spared millions from polio, TB and more via injected vaccines.

5. Personal computer

Altair’s 8800 debuted in 1975 as a hobbyist kit. Two months later, Bill Gates released a programming language for the Altair, and by 1977 the Apple II revealed the PC’s true potential: it shipped with the video game Breakout.

6. Air conditioner

See "Gizmo expos".

7. Telephone

"As a practical man, I did not quite believe it; as a theoretical man, I saw a speaking telephone by which we could have the means of transmitting speech and reproducing it in distant places. But it really seemed too good to be true…" – Alexander Graham Bell, POPULAR MECHANICS, 1912

8. Phonograph

see "Music Machines".

9. Alarm clock

Alarm clocks have been around for centuries, but clockmaker Seth Thomas's 1876 model, planted on the bedside table, helped drag the industrial revolution out of bed.

10. Lightbulb

see "Faceoff".

11. Dry cell battery

See 82 TORCH

12. Bicycle

Chain-driven safety bikes trumped bigwheel "ordinaries" and gave mobility to the masses – particularly bustle-wearing women.

13. Match

The first non-poisonous match wasn’t invented until 1910. Before that, a book of matches packed enough toxic white phosphorous to kill a person.

14. Qwerty keyboard

Christopher L Sholes studied letter-pair frequency and his resulting keyboard layout, introduced in the 1874 Remington Standard 2 typewriter, not only prevented type bars from crossing up, but lasted into the computer age.

15. Modem

In 1949, the first modems (MODulation/ DEModulation) converted air force radar data into sounds and squawked them over phone lines.

16. Transistor radio

See "Music machines".

17. Handheld GPS

After the US military system was opened up for civilian use in 1983, Magellan sold the first handheld unit in 1989.

18. Vacuum cleaner

Although early models were expensive, prices had dropped sufficiently by the mid-1950s to make upright vacuums a middle-class staple.

19. Brownie camera

Inexpensive and easy to operate, the Brownie brought the snapshot to the masses.

20. Remote control

see "Tube Toys".

21. Answering machine

Released in 1971, the Phone-Mate Model 400 was the first widely used example. It was a blessing and a curse: its tapes could capture 20 messages, enabling selective communication.

22. VCR

36. 8 MM Camera

It's the most famous home movie in history: 486 frames that record on Kodachrome II safety film the assassination of US President John F Kennedy.

37. Wristwatch

In 1901, while celebrating in Paris after winning a prize for circling the Eiffel Tower in a dirigible, Brazilian aviator Alberto Santos-Dumont asked his friend Louis Cartier to design a watch that would permit him to time aerial manoeuvres and still keep his hands on the controls. Three years later the Santos men's wristwatch, with leather strap and buckle, went on sale.

38. HDTV

See "Tube toys".

39. Electric drill

See "Man at work".

40. WI-FI Router

Wi-Fi has made its way into more than 9 000 devices, from phones to TVs, since its introduction in 2000.

41. Pocket calculator

The first all-transistor calculator was too heavy to fit into a shirt pocket: the IBM 608 weighed 2 tons. By 1976, four-function pocket calculators were cheap – and pocket-friendly.

42. MP3 player

See "Music machines".

43. Polaroid camera

In 1943, 3-year-old Jennifer Land asked her father Edwin, "Why can't I see the pictures now?" Five years later, Land's company, Polaroid, began selling instant film and cameras.

44. Floppy disc

See "Saving the world".

45. Sony walkman

See "Music machines".

46. Fire extinguisher

The first model (1723) sounds more dangerous than the fire: a cask that held liquid and a pewter gunpowder chamber connected to fuses. At the first flicker of flame the occupant lit the fuses to ignite the gunpowder, which scattered the retardant. We’ve moved on since then.

47. Multitool

See "Faceoff".

48. Game boy

Among the most successful gaming systems ever, with 118 million units and half a million games sold.

49. Circular saw

See "Man at work".

50. Cassette tape

See "Music machines".

51. Lawnmower

See "Man at work".

52. Kindle e-reader

"I'm not a gadget freak, but I have fallen in love with this thing." – Oprah Winfrey

53. Car jack

Richard Dudgeon devised his first hydraulic jack in 1850 for, would you believe it, shipyards and railway repair yards.

54. Ballpoint pen

Hungarian newspaper editor Laszlo Biro took out a patent on the first practical ballpoint in 1938.

55. CB radio

The CB craze of the 1970s was epitomised by Smokey and the Bandit, but like hula hoops, it's now restricted to a tiny minority.

56. Tape recorder

In 1935, AEG came up with a tape-based improvement on existing wire recorders. It wasn't until the next century that digital tech overtook tape in everyday use.

57. Hair dryer

These personal-care staples were created by engineers engaged in building blender motors.

58. Outboard motor

Ole Evinrude's outboard motor was patented in 1911, but it wasn't until post-World War 2 that powerboating became the choice weekend recreation of the upwardly mobile.

59. CD-ROM

See "Saving the world".

60. Moog Synthesiser

Among the first widely used electronic instruments, the Moog had analogue circuits to generate sound electronically. Without it, the Doors’ Strange Days, Simon and Garfunkel’s Bookends and the Beatles’ Abbey Road would have sounded very different.

61. Smoke detector

Duane Pearsall wanted to curb static in photo darkrooms but noticed that a meter measuring ion concentration on his staticcontrol device flatlined whenever cigarette smoke hit it. By accident, he had discovered how to make an ionisation smoke detector.

62. Charcoal grill

There's a good reason it looks like a buoy. Chicago metal-shop owner George Stephen borrowed the same shape – and material-  used in a harbour guide when he built the first Weber kettle in 1951.

63. Lunchbox

When Aladdin Industries launched the Hopalong Cassidy kit in 1950, it kicked off the lunchbox boom: between 1950 and 1970, 120 million lunchboxes shot off US shelves as the youth scrambled to get the latest in branded boxes.

64. Derringer

The derringer used to assassinate US president Abraham Lincoln was actually a deringer with one r. Renowned pistol-maker Henry Deringer's original Philadelphia Deringer, produced from 1852 through 1868, spawned copycats worldwide, and the name – albeit misspelled . became a generic term for any small, large-calibre handgun.

65. Zipper

See "Gizmo expos".

66. Tape measure

See "Man at work".

67. Binoculars

After Pearl Harbour, the Universal Film Company reconfigured its film manufacturing lines to mass-produce binoculars for use in fields where birders dared not tread.

68. Coleman lantern

WC Coleman marketed his Quick- Lite to farmers in 1916, but as electrification spread to rural areas, he rebranded the device as an outdoorsman's essential.

69. Electric toothbrush

US Navy submarines didn't have too much to smile about: subsisting on mushy canned food for months on end, they got almost zero gum stimulation. Electric toothbrushes came aboard 1959, solving the problem. They later found a wider audience – and inspired the invention of another vibrating device (but that's a gadget for an entirely different article).

70. Boombox

See "Music machines".

71. Kodak carousel

Adman Don Draper said it best in his pitch to Kodak execs in an episode of the '60s-set show Mad Men: "This device isn't a spaceship, it's a time machine." He waxed poetic about the Carousel, the ingenious 35-mm side projector, while clicking through images of his family life before it unravelled. "It lets us travel the way a child travels . around and around and back home again."

72. Stopwatch

When the TAG Heuer Mikrograph stopwatch was invented in 1916, it allowed the measurement of time with unprecedented accuracy . down to 1/100 of a second This precision led to significant changes in the sports world, including records such as the world's first sub-4-minute mile (3:59,4 by Roger Bannister on 6 May, 1954). Digital stopwatches, accurate to 1/1000 of a second, debuted in 1971.

73. Printer

Hewlett-Packard's Laserjet cost about R20 000 when it came out in 1984. Today, lasers are cheap, but their ammo isn't: a toner cartridge for a R750 laserjet costs R500.

74. Safety razor

Stay with us now: "Every razor sold represents a saving of half an hour spent in a barbershop… with an approximate number of 10 million customers, this would represent a saving of 5 million hours… (or) 500 000 days of the labour of 500 000 men. (A)t $3 per day (this) represents a saving of $1,5 million per day, or for a year of 300 days, $450 million." – King Camp Gillette, inventor, Gillette Safety Razor, 1918

75. Electric blanket

Breakfast-cereal inventor and sanatorium director John Kellogg advocated sleeping outdoors to promote general wellness. His "thermo-electric" blanket enabled residents to enjoy fresh air regardless of the season.

76. Chain saw

See "Man at work".

77. DVD player

See "Tube toys".

78. Can opener

See "Cook-OMatic".

79. Swiss army knife

See "Faceoff".

80. Spincast fishing reel

In 1949, the Zero Hour Bomb Company faced extinction, with its patent on an oilfield time bomb running out. Plans for an easy-to-use enclosed-spool fishing reel prompted a company name change to Zebco – and the rest is history.

81. Leaf blower

See "Man at work".

82. Torch

The invention of the dry cell battery (11) in 1886 paved the way for the torch, released in 1898. Early versions earned the moniker "flashlight" for their inability to provide a steady beam.

83. Toaster

See "Cooko- matic".

84. Drip coffee maker

See "Cook-o-matic".

85. Sunglasses

Regardless of which Ray-Ban Aviator icon you pick . General Douglas MacArthur during World War 2 or Tom Cruise in Top Gun – it all started in 1929 on the boardwalk in Atlantic City, New Jersey, where Sam Foster hawked America's first mass-produced plastic sunglasses to beachgoers.

86. Hearing aid

According to the USA's National Institutes of Health, only one out of five people who could benefit from a hearing aid actually wears one.

87. Ginsu knife

For better or worse, the ads for these blades ushered in the era of the infomercial tout: "But wait – there's more."

88. Flash drive

See "Saving the world".

89. Teflon pan

See "Cook-o-matic".

90. Zippo

The Zippo moment . when a concert audience raises its lighters in the air – has been rocking the power ballad since the '60s. In 2008, the company introduced an iPhone app for that: the digital Zippo operates just like the real thing, opening with a flick of the wrist, lighting with a swipe of the flint wheel and mimicking real flame movement as the user waves his phone in the air.

91. DVR

See "Tube toys".

92. Picnic cooler

That tub you use to chill beer was patented in 1951 as a "Portable ice chest for storing foods and the like".

93. Bra

"I can't say the brassiere will ever take as great a place in history as the steamboat, but I did invent it." – Mary Phelps Jacobs, who in 1914 used handkerchiefs, ribbon and cord to create an early vision of the bra.

94. Blender

See "Cook-o-matic".

95. Super soaker

Since 1990, no fewer than two dozen Super Soaker models have wrought backyard mayhem, but none is more coveted than the CPS 2000 Mk1. The most powerful water gun ever manufactured, it shoots nearly a litre of water per second up to 15 metres. The Mk1 was discontinued soon after its release, but it's available on eBay for a cool R2 000.

96. Quick-release ski bindings

Champion skier Hjalmar Hvam invented the Saf-ski system while recuperating from an accident aggravated by fixed ski bindings. Local relevance: the ubiquitous clipin pedals used by cyclists were pioneered by Look, who drew on their own experience in clip-in ski bindings.

97. Aerosol spray can

In 1941, Lyle Goodhue and William Sullivan used the newly discovered refrigerant Freon to enable the deployment of a lethal (to bugs, anyway) mist by troops fighting on insect-infested fronts. The "bug bomb" cocktail, held in a 500 ml steel canister, consisted of Freon-12, sesame oil and pyrethrum (the last is a natural insecticide derived from chrysanthemum blooms).

98. Roomba

Before it unveiled the Roomba Floorvac for the home market in 2002, iRobot built landmine-clearing robots, which used the so-called crop circle algorithm. The same tech was adapted to enable the Roomba to circle and sweep autonomously. The device is far and away the best-selling mobile robot.

99. Stapler

Said to date back to the 17th-century French court, the stapler as we know it was patented in the 1800s.

100. Glass fibre fishing rod

When hostilities in Asia curtailed bamboo imports, rodmakers needed a new material to keep anglers equipped with low-cost, quality tackle in the 1950s and 1960s; enter glass fibre.

101. Duct tape

Astronauts have used it to make repairs on the Moon and in space. The Myth- Busters built a boat with the stuff. And enthusiasts have used it to make party dresses and wallets. You might say it's a material, not a gadget, but trust us: duct tape is the ultimate multitool.
