Apple revolutionized the way we listen to music through iPod, it changed the way we see phones and connect online by making iPhone and soon, the company will enter the education industry through digital textbooks.

The textbook business generated nearly $5 billion dollars last year, according to the American Association of Publishers, but digital textbook sales only account for about 6 percent of that number. But, with the growing number of e-readers and tablets among students, those numbers are expected to go up.

Here is what the digital textbooks have to offer:
• A quicker means of study being able to swipe to different pages and links;
• Rich, engaging layouts that make books far more engaging than print media;
• The ability to embed movies into textbook pages;
• An additional dictionary component. If a student does not understand a word on a page, they are able to bring up a glossary definition immediately;
• Toolbar search facilities;
• Review questions to help students test their knowledge on a book chapter or film;
• A portrait and landscape mode switch feature;
• Users ‘own' the book for life, enabling them to re-download texts at any point from the cloud.

Apple's announcement to market with other companies expected to enter the digital textbook fray digital textbooks for publishers could mean old-school books and the days of student backpacks weighed down by heavy books could eventually become a thing of the past.

It is a tough challenge to make people change their old ways that are being followed for centuries. Hope Apple comes up with something magical that changes everything.
