"These numbers show there is a growing hunger for local Chicago area news, sports and commentary. The Sun-Times News Group is delivering increasingly robust products online that are clearly showing results in the data we are seeing," Cyrus F. Freidheim Jr., president and chief executive officer of STMG said in a statement.

Meanwhile, the average amount of time spent on Sun-Times Media Group Web pages also increased to nine minutes and 10 seconds. According to Nielsen/Net Ratings, the group ranks among the top 10 most popular newspaper sites, with 3.5 million unique visitors each month.

Suntimes.com, rogerebert.com and searchchicago.com/autos all show particularly strong traffic growth, E&P reported.
