liqs8143 writes with news that IBM's market cap has surpassed Microsoft's, making it the second most valuable tech company. When the market closed on Friday, IBM was valued at $207.52B, while Microsoft was valued at $206.52B. "At one point during the PC era, Microsoft's value climbed three times higher than IBM's. Apparently, this has been a long two decades in Armonk, N.Y., but Microsoft also is no longer the beast it once was. The guard is changing. Besides Apple, there is also Google. While Google is valued at about $170.59 billion, less than the other three, its $31 billion in annual revenue is half of Microsoft's $69 billion and less than a third of IBM's $101 billion. Waiting in the wings is Facebook, which has been valued in the private market for as much as $50 billion, on negligible revenue."
