With the way that the internet has really taken off and has expanded beyond what most people ever expected, there have been some major shifts in a number of industries, as well as brand new industries that have cropped up seemingly overnight. At the same time, media has become widely “digitized” and consumers can access many types of digital products. Audio book store websites are evidence of these changes.

Nowadays, anyone who has an internet connection and a desktop computer, a laptop computer, or a WiFi enabled PDA, has easy and convenient access to a mind-boggling selection of MP3 audio book titles that are available from any number of audio book store websites. With the growth in popularity of audio book downloads and being able to listen to all kinds of books — from classics, to brand new releases, to obscure niche topics — as audio recordings, there is no doubt that this is going to be a strong and flourishing industry for the foreseeable future.

Most of the audio book store websites that can be found have an extremely wide selection of topics to choose from. You can download MP3 audio book titles from just about every category, from fiction, to biographies, to business, to self-improvement, to brand new audio book releases from bestselling authors.

One of the reasons why audio books on all kinds of topics have become so popular is that many people consider that time wasted is the same as opportunity wasted. When stuck in a car for an hour or two every day while commuting to and from work, there’s a great deal of time that can be put to better use and listening to audio books while commuting can turn the car into a university on wheels. People have been known to make amazing improvements in their lives just by taking advantage of all the learning that they can take advantage of through listening to audio books on the road.

Audio books are great to listen to during a commute, while traveling for business or pleasure, while exercising, or while pursuing hobbies. It is simple and easy to pick up a new audio book any time that you are in need of something new. With audio book downloads that the online audio websites offer, you will instantly have your book to play on your iPod. There is no more waiting for the mailman to deliver the audio book on CD and no longer any need to pay for shipping and handling.

These days there has been such an escalation in the number of audio book store sites online that this particular niche industry has gotten to be extremely competitive. The good news is that when websites are competing with each other, the consumers are the winners. Competition helps to keep prices from going up and helps to motivate the retailers to carry better selections and often these audio book stores will offer a free audio book with every purchase, or discounts on multiple purchases. With all of this going on, it is making it easier than ever for consumers to always have a new audio book to listen to and relax with.

There are numerous people who express surprise when they learn that audio books have been available ever since the 1930s, even though they were not widely available until many years later. Now, some eighty years since that time, more and more people are listening to what used to be called “books on tape.” However, in this digital age, audio books are not often found on tape. MP3s are more popular. Even more popular are free MP3 audio book downloads that allow people to put the recording on their computer or iPod, without spending a nickel.

Even though audio books had been available for a number of years, they really gained in popularity in the late 1970s when the Sony Walkman became so popular. This small cassette tape player made it possible for people to easily take recorded material with them in a convenient way that had never before been popular. Then, about a decade later, the compact disc was introduced and suddenly the newest and best music and audio books on CD became more popular. While you can still buy an audio book on CD today, most people prefer to get their audio books in MP3 format.

There is no doubt that a little searching will produce a wide array of free MP3 audio book downloads from a number of websites. However, it is pretty unlikely that if you are looking for a brand new audio book release of a recent bestselling book that you’ll find it as a free download. Those new and popular titles will be available for sale though, and many via a download after purchase.

In some instances, an author, or their publisher, will offer a free MP3 audio book version of the work to customers who purchase the printed hardcover book. This can be a valuable incentive to the customer and also an effective advertising and marketing strategy that is particularly helpful when a brand new author is trying to gain a name and reputation.

Many times, an independent author who does not have their own publisher will build a website to promote a new book that they have written and will offer the free MP3 audio book as a bonus when the customer buys their printed book or their e-book. This can also be a good way to drive up sales or to launch a new website because people are always attracted to the potential to get something for free and most people consider an audio book download to have a lot of value, especially if it is on a topic about which they are interested.

There are a number of websites these days that have vast libraries of MP3 audio book downloads that cover just about any topic that have ever been written about. Some of these sites are membership websites and when you register as a free member or purchase a paid membership to their site, many will provide their new members with free MP3 audio book selections as a part of their membership.

You can also find many free MP3 audio book downloads by searching the websites of the various large public libraries. Also, there are some specialized websites that have undertaken projects of collecting a vast number of works that are now in the public domain and they have made e-books and audio books available for people to download either for free or by making a small donation to help with the costs of running the website.
