It gives me great pleasure to see that the Fourth Edition of this book is being brought out in an entirely new and attractive format. It is also a thoroughly revised and enlarged edition. In view of the growing importance and expanding avenues of Business Communication the writer has thoroughly looked through all the chapters once again and updated them with the latest information wherever needed. A new chapter entitled “Brands vis-a-vis Social Networking” has been added to the book. The whole idea is to make the book more interesting and useful to the students as well as the general readers, who have been continuously patronizing it since its first appearance. The writer is indeed indebted to innumerable friends and colleagues for their suggestions. Fruitful discussions with management students have also gone a long way to give the book its present shape. Further suggestions for improvement are welcome and will be gratefully acknowledged. Any shortcomings, wherever noted, are the writer’s own.
