  • Thoughts on Flash
    Apple has a long relationship with Adobe. In fact, we met Adobe’s founders when they were in their proverbial garage. Apple was their first big customer, adopting their Postscript language for our new Laserwriter printer. Apple invested in Adobe and owned around 20% of the company for many years. The two companies worked closely together to pioneer desktop publishing and there were many good times. Since that golden era, the companies have grown apart. Apple went through its near death experience, and Adobe was drawn to the corporate market with their Acrobat products. Today the two companies still work together to serve their joint creative customers – Mac users buy around half of Adobe’s Creative Suite products – but beyond that there are few joint interests. I wanted to jot down some of our thoughts on Adobe’s Flash products so that customers and critics may better understand why we do not allow Flash on iPhones, iPods and iPads. Adobe has characterized our decision as being primarily business driven – they say we want to protect our App Store – but in reality it is based on technology issues. Adobe claims that we are a closed system, and that Flash is open, but in fact the opposite is true. Let me explain. First, there’s “Open”. Adobe’s Flash products are 100% proprietary. They are only available from Adobe, and Adobe has sole authority as to their future enhancement, pricing, etc. While Adobe’s Flash products are widely available, this does not mean they are open, since they are controlled entirely by Adobe and available only from Adobe.

Flash is an Adobe trademark that is used with Adobe’s multimedia authoring and playback systems based on its family of Flash software products, also referred to as Flash technology. Use of the Flash trademark should always be in compliance with Adobe’s Trademark Guidelines, which state in part that third parties may not incorporate or include, in whole or in part, any Adobe trademark into that third party’s company name, product name, service name, trademark, logo or Internet domain name. You can find these general guidelines online at www.adobe.com/misc/agreement.html.

Companies who are not Adobe licensees but who claim to have technology that is compatible with Adobe Flash products may claim, if true, that their products are “compatible with Flash X” as long as nothing in the circumstances would create consumer confusion.
