Google shares jump 20% on first day's trading

In the most highly-anticipated Wall Street debut since the heady days of the dot-com boom, shares of Google surged nearly 20% on their first day of public trading as the quirky internet company completed its much-hyped initial stock offering.

Despite the first-day jump yesterday, the debut generated much less money than the company envisioned after it launched an unorthodox auction designed to open the stock beyond large investors who typically get first crack at new stock issues.
