The internet has a lot to do with the need and expansion of audio conferencing. Many companies are hiring employees that are working all over the globe. It can get expensive and impractical trying to meet face to face. Audio conferencing is great for the work-from-home employee because it can be attending in pajamas, which means no matter what the time where you live, you are ready to sit in on the conference. VoIP is another reason that the internet is increasing the use of audio conferencing. With Voice over Internet Protocol, it is possible to call anywhere in the world for little or nothing. Some VoIP services even come with audio conferencing features. cnn money
