MacDailyNews reports that Apple is advertising Mac OS X 10.4 (Tiger) in Time Magazine.

The two page print ad shows two Apple Cinema Displays demonstrating Spotlight and Dashboard technologies.

Find Stuff: Mac OS X Tiger. The world's most advanced operating system now puts even more power at your fingertips. With new features like Spotlight, Mac OS X's amazing search technology that lets you instantly find anything on your Mac - documents, e-mails, contacts, bookmarks, images, even things inside PDF files.

Find Out Stuff: And Dashboard, a whole new world of timesaving widgets. Instead of having to visit multiple websites for things like weather forecasts, stock queries, business listings or airline flights, Dashboard brings it all to you instantly, then disappears instantly so you can go back to what you were doing. Just two of Tiger's more than 200 new features that will change how you use your computer.

There have been rumors that Apple would be organizing a Mac ad campaign in the near future, but rumors had hinted at switcher-themed ads rather than Mac OS X specific features. Its unclear if Mac OS X Tiger television ads will follow.

Update: The same ad can also be found in Fortune, The Economist, The New Yorker, Newsweek, and BusinessWeek according to readers.
