Google's shares hit an all-time high on New York markets yesterday, making Google the biggest media company by stock market value. Google's total stock market value was $80 billion yesterday.
Time Warner takes the second spot with a value of $78 billion. Though some analysts believe Google's shares are way overpriced as Google only had annual sales of $3.2 billion while Time Warner's annual sales accounted for $42. But others believe the high stock value reflects Google's future earnings potential and say that it might even hit $325-350. More details at BBC
