Slick interfaces and bundling helped solidify Excel as the corporate planning tool

First initiated in the 1980s, the Excel spreadsheet built off predecessors like Lotus and VisiCalc, leveraging a novel graphic interface to entice new customers and packaging the program with other Microsoft Office products. Forty years later, the tool faces challenges from Google and AI, but retains devoted users.

Aiken, the IBM Mark I was a groundbreaking machine used to solve ballistic trajectories and other mathematical problems whose solutions were needed for the design of the atomic bomb in World War II. The device was one of the first mechanical computers.

The first computers performed calculations using lightbulb-like tubes

Before transistors, the first electronic computers relied on vacuum tubes—components that switched signals on and off. Despite machines like ENIAC—the first programmable, general-purpose, electronic computer—utilizing nearly 18,000 tubes that generated massive amounts of heat and frequent failures, they laid the foundation for modern computing hardware.

The first computer virus was created by a USC doctoral candidate in 1983

A year after creating malware in a controlled experiment that multiplied until it took over all of a computer's memory, Fred Cohen went public with his research and its risks. He called the self-replicating software a "computer virus," a term Cohen's advisor, Leonard Adleman, coined to describe its infectious behavior. (Some readers may experience a paywall.)

The first smartwatch was made by Microsoft in 1994

Coproduced by Timex, the Timex DataLink 150 featured a small LCD screen and could transfer data to and from a Windows PC. Like the Windows XP Tablet that launched in 2002, the smartwatch did not sell well, and both products are considered to have been released before their time.

The software for wikis—user-editable websites—was launched in 1995

Computer programmer Ward Cunningham created the WikiWikiWeb online application based on an offline system that helped track how ideas moved through his company. The application enabled users to collaborate and edit website content through a web browser, as well as link pages without requiring a structured navigation scheme.

The first portable laptop had a 5-inch screen and weighed 24.5 pounds

Introduced in 1981 for $1795, the Osborne 1 had no battery but came bundled with almost $1,500 worth of software. Early announcement of a future model stalled sales and bankrupted the company as users waited for the more advanced version, a phenomenon now called the Osborne effect.

The world spent up to $600B to avert the Y2K computer glitch

Early computer programmers used a two-digit code to record years rather than four. With the switch in the year 2000 from '99 to '00, analysts feared databases might fail and prompt outages and financial catastrophe. To prepare, governments and businesses spent an estimated $300B to $600B to mitigate the glitch.

Silicon Valley gained its name from an article published in January 1971, in Electronic News. Author Don Hoefler used the term in his headline for an article he was writing about the semiconductor industry. Hoefler is credited with naming the multi-trillion dollar area that is still called Silicon Valley today.

A technological breakthrough altered how Billboard determined what was popular

Before 1991, retail stores manually reported sales to Billboard, which then used those figures as part of its calculations for its weekly charts. In 1991, the magazine began using Nielsen SoundScan, a technology that tracked every unit sold in participating stores, providing a more accurate picture of what consumers were actually buying.

The Fair, Isaac and Company (FICO) was founded in 1956

But once office telephones and computers became commonplace, banks and other financial institutions didn't necessarily need to have their headquarters near exchanges like Wall Street's New York Stock Exchange.

Early MBA curricula were influenced by a movement in ‘scientific management’

Visualizing how changes to lineups would impact historical baseball games

This visual essay maps how data-informed lineup construction has revolutionized baseball. Amid the embrace of analytics, the game's best overall hitters were moved from the third spot to second, power bats were shifted out of the "cleanup" role, and speedsters—typically the leadoff batters—were pushed to the bottom half of the nine-player lineup. Joe Carter, the hero of the '93 World Series, likely never hits his iconic walk-off from the cleanup spot in a modern lineup.
