The picture on the left shows the trend for online search volume for "ISB" and in the lower part shows how often the word "ISB" was referenced in online news.
Two trends are clearly visible. There was a huge surge around 'E', early april that an ISB student had bagged a 1 crore salary. On the news reference trend, onve can see the trend line really taking off after the Bush Visit and continued to rise higher with announcements of placement results and even higher with announcements of profile of batch of 2007 (Marked 'F' ).
The two events have generated massive publicity and good PR for the Indian School of Business.
