But much like the industry that supported his 26-year rise Wolf has discovered that brazen bravado has its limits.

Back then the Internet was just starting to become an integral part of daily life and Netscape Navigator and Microsoft Internet Explorer vied for control of the market. This time around the browser battle includes an increasing number of competitors most notably Internet Explorer Mozilla Firefox and Google Chrome. Newcomers like RockMelt a start-up that promises to integrate web browsing with social networking are banking on innovative new features to stand out. But does winning the browser space mean much in environments -- like mobile devices -- that increasingly focus on standalone web-connected apps?

After years of declining market share and unprofitability -- and a multi-million dollar bailout by the United States government -- General Motors is once again a publicly held company. The automaker which raised some $20 billion through last week’s initial public offering is on sounder footing than it has been in years. Yet the new GM still must compete in a tough global market. So the question remains: Can the new GM perform better than the old GM? Knowledge at Wharton posed this question and others to Wharton management professor John Paul MacDuffie.

In the U.S. infrastructure is usually silent and forgotten -- until the power goes off the ATM stops working or a neighborhood is consumed by fire. In September a 54-year-old gas pipeline exploded in San Bruno Calif. killing eight people and damaging more than 50 homes. Seven weeks earlier an oil pipeline rupture in Michigan spilled more than a million gallons of crude. According to experts the country’s infrastructure is a huge market that holds tremendous business opportunities but the bulk of entrepreneurs and investors still wait on the sidelines because the projects are costly complicated and often risky.
