Products can be too popular for their own good. Take zipper, for example. Today, it’s used as a generic term for the interlocking steel teeth that keep you from exposing yourself to the public, but in the 1920’s, it was a distinct brand: the Zipper, invented and marketed by B.F. Goodrich, which was such a successful alternative to the boring old button that it lost its capital ‘Z’ in the mind of the public and became a generic term that lost its trademark… and once it lost its trademark, anyone could call their rip-off product a “zipper” as if it was the real thing.

It’s a very real issue that many companies spend a good deal of money on every year. They want their brand to be synonymous with a certain type of product, but they don’t want it to be so synonymous that they lose ownership of the brand. And it’s why, if you like, say, Jell-O, or Xerox, or Kleenex, you shouldn’t refer to similar products from another company by the same name.

Over at The News Virginian, there’s an interesting think piece by AP writer Mae Anderson if the same thing could happen to the iPad. It’s a great read on the history of trademarks becoming generic, but it’s not really very likely to happen to the iPad. Here’s why.

When Apple announced that it was bringing movies and TV shows purchased in the iTunes Store to iCloud, every major production house was onboard except Universal and Fox. Due to licensing conflicts with HBO, Universal and Fox were not able to offer video content in iCloud initially. HBO later said that it would be loosening its grip on the studios to allow for licensing agreements with Apple.

It now appears that Universal Studios has been able to start offering its movies in the iTunes Store for re-download in iCloud.

Celebrity physicist Brian Cox is famous in the U.K. for making physics accessible to the public through bestselling books and several popular TV series. Now he brings elements of both to a gorgeous new iPad app: Brian Cox’s Wonders of the Universe ($6.99).

Featuring amazing animations and lush, high-production video, the app will sweep you back in time to witness the Big Bang, and then look ahead to the universe’s end, when the last black dwarfs will fizzle away to entropy.

As Prof. Cox points out: while the universe evolves momentarily from order to chaos, now is a precious window of time when life is briefly possible, for us to be able to contemplate the universe…

Whenever Apple launches a major new product, massive billboards usually go up within days. I know this, because my commute along San Francisco’s 101 freeway passes three giant billboards on the way into the city.

Year after year, I’ve seen the ads go up within days of the new product’s launch. Last year, ads for the iPad 2 were posted almost immediately after the device’s introduction by Steve Jobs.

Thing is, those same iPad 2 billboards are still there. Two weeks after the launch of the iPad 3, the billboards along 101 are still advertising the old iPad 2.

It seems to be the same situation across the country. We’ve been talking about this for days, and no one on the Cult of Mac staff has seen a outdoor ad for the new iPad.

What does it mean?

There are now over 500,000 iPhone apps and 170,000 iPad apps available on Apple’s App Store and that number will surely continue to increase as new app developers enter the foray. In March 2012 Apple’s App Store surpassed its 25 billionth download. If you’re not already buying apps regularly, you probably will be soon. Here are some tips that may help you save some money on your App Store purchases.

External batteries for our Apple notebooks aren’t cheap, but they’re hugely worthwhile if you’re frequently on the road with little access to a power outlet. But before you shell out $250 for a ready-made solution, why not make your own for less than $60?

Apple broke away from its traditional June iPhone unveiling last year, delaying the iPhone 4S announcement until early October instead. The company is widely expected to do the same with the iPhone 5 — likely to be called the “new iPhone” — this year, but according to one Foxconn recruiter, it’ll arrive in June like many of its predecessors.

Barefoot Books World Atlas ($8) is a kind of digital globe for children, giving them easy access to a simplified cartoon overview of the whole world.

From the orbital view (for want of a better word), you see the globe peppered with hundreds of colorful icons. Spin the globe and zoom in. The little icons grow and become tappable controls. Each one reveals a snippet of information in text and audio form (read aloud by the UK’s favorite TV geographer (yes, we have those), Nick Crane). There’s also a photo to look at for each fact, which is often much more informative than the icon was to start with.

Bleeding hearts the world over are very happy with the news that Apple and Foxconn are working together to make employee working conditions better in their Chinese factories. But there is a group of people who aren’t so pleased about the reductions in working hours: the workers themselves.

Looking for a great deal on the tablet that proved to manufacturers that price matters? Amazon is offering up certified refurbished Kindle Fires at a ridiculous price of $139. It’s a limited time, limited quantity deal, so you’ll want to act fast. The Amazon Kindle Fire blazed into the tablet market with its perfect price and treasure trove of content.
