USA Today’s David Lieberman writes about how business news has become big business…

“Business is growing again,” says Christopher Poleway, former president of The Time Inc. Business and Financial Network, which includes Fortune, Money and CNNMoney.com. “Earnings are strong. Innovation is strong. There are a lot of start-ups. There is a lot of venture capital again supporting new ideas. So it’s become exciting again.”

Leaders in the field say that many people likely will stay focused on business news even when the market cools. That’s because the median age of the population is rising, swelling the ranks of people who must save and invest for major expenses, including their kids’ education and retirement.

“The big bang (for business news), if there was one, was the realization by people like me that the Social Security system is not going to be around for us when we get ready to retire,” Roush says. “We have to take care of our retirement by putting together an IRA or 401(k) plan.”

“There’s a nation of investors hungry for this information,” he says. “Today’s business news is different than it was 10 years ago. It has changed as the markets have, as real estate has, as equities have and as options trading has. Equities trading is up something like 8% this year. Options trading is up 30%. That tells you people are trying to make money in different ways.”
