Do you own an MP3 player, a cell phone or a laptop?
If you're like most people the answer is an instant yes to at least one of those.
But do you also own speakers, a carrying case, fancier earphones, a remote or some other accessory to use along with it?
If your response was also in the affirmative, you're not alone. It's just what the electronics industry was quite literally banking on.
While manufacturers of all those gadgets and gizmos you carry with you everywhere are making more than a small fortune selling those things to you, they're also faced with a real dilemma.
Once you've made your purchase, you don't need to go out and buy another one.
Enter the accessory.
Companies are now often making more from all the extras that go with a best selling product than they are for the original item itself.
In a survey released this week, the Consumer Electronics Association predicts the market for all those add-ons will grow 11 percent this year alone, generating some $11 billion in profits and exceeding the projected growth rate of the entire industry.
It seems once you buy those 'must-have' items, you must have everything else that goes along with them.
The industry group estimates consumers spend an average of 15 percent of the original cost of their device buying other things to use with it.
"The MP3 player is the perfect example of a new product that fueled an explosion of attachment products," explains the Association's Tim Herbert. "Changes in consumer behavior can have an even bigger impact, however. Consumers now conduct business or manage their personal lives anywhere at anytime.
"This has created an entire class of accessory products designed to enhance and support this "on-the-go" lifestyle. Products such as Bluetooth headsets, portable Flash storage and portable speakers for MP3 players are examples of accessories created as a result of these changes."
Among the most popular: speakers, headphones, adapters and battery chargers.
A quick check of a national electronics chain in Canada confirms there are actually more extras than products on sale. You can buy additional cables to hook your iPod into a computer or stereo, stands to put up those extra speakers; additional back-up batteries; universal remotes and memory extenders - just to name a few.
And the research shows you buy most of this stuff long after you've made the original purchase and discovered what it is you're missing.
"With the right mix of accessories, customers are more satisfied with their purchase and are less likely to return products," Herbert concludes.
So expect to continue to see an endless line of new accessories the industry will tell you can't live without hitting store shelves over the next few years.
Because they don't have all your money yet. But they're working on it.
