It is a marketing strategy that few experts would recommend and even fewer companies can pull off.
But the less Apple says about its eagerly anticipated event on Tuesday at a performing arts centre in Silicon Valley, the more frenzied the speculation becomes.
In keeping with its style, Apple has revealed little about what is expected to be the unveiling of the company's first "big thing" since the death of legendary co-founder and driving force Steve Jobs nearly three years ago.
Invitations sent out to a select crowd had only the date and the cryptic message: "Wish we could say more".
Apple is a proven master of getting more attention by saying nothing than most companies do by pouring money into marketing campaigns.
As long as Apple keeps cranking out must-have devices, silence and selectivity should remain potent weapons in its marketing arsenal, experts say.
"There is the culture of secrecy, which fuels a lot of speculation about what they might be doing," Reticle Research principal analyst Ross Rubin said.
"And there is this expectation that the products they introduce are going to change the game. Backing it up is a really incredible track record dating back to the Apple II (computer)."
The strategy of letting rumour mills crank up expectations puts pressure on Apple to repeatedly wow the world - or risk having events branded as disappointments.
But Apple has been known to reach out behind the scenes to temper grandly unrealistic speculation.
Apple is even seen as becoming slightly more open after the departure in May of Katie Cotton, a communications executive who firmly managed the company's precious image.
In the past two weeks, traditionally taciturn Apple was quick to release statements after hackers swiped nude photos of celebrities from iCloud accounts and in response to a report critical of one of its suppliers in China.
Some say that Apple's inclination to lock secrets behind its campus walls stretches back to when Jobs in 1997 returned to the helm of a company that was on the ropes with the world ready to count it out.
A pair of longtime Apple engineers once suggested to AFP that the marketing technique stemmed from Zen Buddhism studied by Jobs, and the notion that media attention is naturally compelled to fill the void left by the company remaining mum.
The practice has been a winner for Apple. No venue seems big enough for its launch events, and it grabs headlines in weeks leading up to and following announcements.
People rush to snap up new Apple gadgets.
Reasons that Apple thrives while being aloof include the technology titan's focus on doing a few products amazingly well, while controlling everything from hardware to operating software and content.
Apple even started making its own chips for mobile devices.
Among products Apple got right is the iPhone, which has become the company's main money maker.
Apple profit climbed in the second quarter of this year with strong demand for iPhones, particularly in China, where the company's revenue surged.
Apple said it sold 35.2 million iPhones in the quarter, a rise of nearly 13 per cent from the same period a year earlier.
During an earnings call with financial analysts, Apple chief executive Tim Cook boasted "incredible" new products and services were on their way - but typically, didn't reveal specifics.
