More on the Portfolio.com relaunch

American City Business Journals, the new operator of Portfolio.com, released some interesting details Monday about its relaunch of the business news site.

Portfolio.com’s series The Great Global Business Adventure, now underway, will run for a full year and is the product of embedding a reporter with a group of business owners exploring international expansion.

Another series, The New Risk, next looks at whether steps taken because of the economic crisis are really improving financial stability, concludes in January. In the first of what will become regular reports on emerging national trends, the site this week looks at how solar energy is being adopted by small and mid-sized businesses and the impact of community banks closing across the country.

Also on Monday, Portfolio.com launched “U.S. Uncovered,” a special section showcasing monthly demographic reports about the nation.

In addition to original content, Portfolio.com will draw from the journalism being produced by the local ACBJ business journals as well as select content from Conde Nast titles, such as Wired and Vanity Fair. On Monday, the site showcased an investigation from the Puget Sound Business Journal on why Federal regulators shut down Washington Mutual.

Portfolio.com also included an exclusive business news aggregator called bizWatch that can be fully customized by keyword or ticker symbol to track more than 9,000 public companies from thousands of news sources.

During the next few weeks, the content will expand to more than 200,000 companies that can be tracked, along with some 500,000 executives.
