Yahoo India will soon be deprived of its managing director – reports indicate that George Zacharias has put in his “four-to-six week notice.”  After concluding his career with Yahoo, Zacharias intends “to pursue his own entrepreneurial interests.”

Yahoo and Google both appear dedicated to growing their presence in the Indian market, and to this end, Yahoo recently announced that it had bought a stake in Tyroo Media.  Call this one a “significant investment” (as Yahoo does) – it’s equal to about 35% of the company’s value.
