Gannett Co. said its first-quarter earnings soared as growth in the media company's broadcast and digital businesses offset declines at its publishing division.

Gannett has been aiming to boost the performance of its newspaper operations by inserting content from its flagship USA Today into some of its local newspapers, an effort it recently expanded to other newspaper groups. It follows similar programs launched by the Washington Post and the New York Times last year offering supplements of their content to other newspapers.

In the latest quarter, publishing revenue declined 8.8% to $768.2 million, reflecting softness in print advertising, the sale of Gannett Healthcare Group and the ceasing of publishing of USA Weekend at the end of last year. Advertising revenue fell 11% to $444.4 million, while circulation revenue dropped 3.1% to $273.2 million.

Gannett said it remains on track to spin off the publishing business from its more lucrative broadcasting business in mid-2015. With the separation, Gannett will join other media companies that have or will spin off print-publishing operations from faster-growing television and digital operations.

Gannett greatly expanded its broadcast operations with its $1.5 billion acquisition of broadcaster Belo Corp. in late 2013, and has continued to bulk up its digital properties. In October Gannett completed the acquisition of the 73% interest it didn't already own in Classified Ventures LLC, which controlled Cars.com.

In the latest quarter, Gannett reported that its broadcast revenue increased 3.8% to $396.8 million, mostly driven by 26 growth in retransmission revenue that offset the impacts of year-earlier Olympic and political advertising spending.

Overall, Gannett reported a profit of $112.9 million, or 49 cents a share, up from $59.2 million, or 25 cents a share, a year earlier. Excluding items, year-earlier per-share earnings were 47 cents. Revenue increased 4.9% to $1.47 billion.

Analysts polled by Thomson Reuters expected per-share profit of 45 cents and revenue of $1.52 billion.

Digital-segment revenue, which is reported separately from digital revenue in the publishing division, soared 85% to $332.7 million, mostly on results from Cars.com and continued growth at CareerBuilder.
