Today during a conference call, I was thinking about the time when a message required at least 48 hours to get delivered from one state of America to the other via ponies or trains. Time has brought revolutionary changes in business communication. Nowadays we can complete a small business project by 4 to 7 days and can do instant communication whenever required. Apart from business IM and online video calling, conference call is a communication tool which is taken for granted and its significance is not actually realized. It is because of the availability of advanced virtual collaboration tools such as video calling and screen sharing. However, conference calls have played their worth mentioning role even before the first business email which was sent in 1971 through Arpanet. Just like online video calling, conference calls, technology has gone through many innovations. Some of these are mentioned below:
