Whether the next administration will see fit to revisit these regulations remains to be seen, but for IT there's no going back. Regulatory compliance has cemented its position as a key component of business operations, for better or for worse.

Apple Flips Its Chip Strategy
The Macintosh has always stood apart, even before Apple launched its "Think Different" ad campaign in 1997. In defiance of the x86 platform's dominance of the PC chip market, the earliest Macs used Motorola 68000-series CPUs. Later, when performance demanded an upgrade, Apple switched to the PowerPC, but the net effect was the same: Macs and PCs were as fundamentally different as, well, apples and oranges.

But Apple couldn't fight the tide forever. Performance bottlenecks and high power consumption dogged the PowerPC, and by 2005 its future as a general-purpose processor seemed doubtful. In June of that year, Apple announced that it would begin shipping Macs based on Intel processors, ending 20 years of Thinking Different about CPUs.

In so doing, the PC processor market effectively became a monoculture. Virtually every mainstream computer you can buy today is based on Intel's architecture. Macs can even run Windows. But it's OK, Mac fans; if what's inside doesn't make you feel different, how it looks still can.

Outsourcing Goes Global
As the year 2000 approached, U.S. companies saw the Y2K problem as a threat to their software. What they didn't anticipate was the impact it would have on the American workforce.

Faced with a shortage of hands to address the Y2K crisis, IT departments looked abroad for answers. They found an untapped gold mine. The rise of the Internet, coupled with social and economic reforms, had fostered a veritable army of highly skilled workers in the developing world.

Indian companies, including Infosys and Wipro, were among the first to popularize offshore IT outsourcing, but companies in Russia, Eastern Europe, China, and elsewhere would soon follow. Meanwhile, the Immigration Reform and Control Act of 1990 had created the H-1B visa program, which made it easier for U.S. companies to import foreign workers.

Today the Y2K problem may be long behind us, but these trends show no sign of slowing. As more and more countries awaken to the Internet economy, IT workers must struggle to stay competitive in an increasingly flat world.
