After a TechCrunch report said that Amazon.com had already sold 240,000 Kindles this year, Wall Street analyst Mark Mahaney called the Kindle "the iPod of the book world." Now Amazon.com says both Mahaney and TechCrunch spoke too soon and without talking to the right people. The right people, according to analysts from McAdams Wright Ragen, being analysts from McAdams Wright Ragen.They say Amazon executives told them "high-end estimates on Kindle sales reported by TechCrunch and a Citigroup analyst are not reasonable." Writes one of the McAdams Wright Ragen analysts: " told us that the Kindle is definitely selling very well, but they also said the analysts and reporters giving out these extremely high estimates 'did not run them by company. Since we've never seen a Kindle in person, we're inclined to believe the Amazon executives when they say the Kindle isn't quite such a huge hit. But the suits might also be trying to keep expectations low enough to be easily surpassed.

In February, ComScore reported underwhelming growth in clicks on Google ads in the U.S. Google shares sank below a 52-week low for the first time in the company's history. Then, yesterday, Google reported 42 percent year-over-year revenue growth, surpassing expectations. Burned, Wall Street traders reacted harshly toward ComScore, dropping the company's shares by 8.4 percent after hours. Today, ComScore wants to remind the world that it never said Google's revenues would sink and that it only measures clicks on Google ads in the U.S., not internationally But really, Google investors owe ComScore a large debt.

Wall Street analysts don't believe Yahoo revenues will grow 72 percent by 2010, as the company argued yesterday in a shareholder presentation. JPMorgan analyst Imran Khan said Yahoo's estimates for its 2009 revenue, $7.1 billion, exceed his own by $700 million. He doesn't believe Yahoo will own enough search market share to hit those targets. "Those are not easy numbers," Citi analyst Mark Mahaney told the Wall Street Journal. "The most likely outcome that Microsoft buys Yahoo, and at a higher price than $31," he said. (Photo by Todd_Cliff)
