At a time when many news organizations are cutting back, the Corporation for Public Broadcasting is continuing its efforts to bolster in-depth journalism in public media. The corporation said on Tuesday that it was giving “Frontline” a $6 million, two-year grant that would allow it to expand its investigative programming to a year-round schedule on PBS stations.

The money, plus an additional $1.6 million that is still being raised, will pay for seven to eight new programs each year, so the 28-year-old show will no longer have to take a summer hiatus. The expansion was announced in Austin, Tex., at PBS’s annual meeting.

The corporation’s investment was “brought on by the recognition that there’s a crisis in journalism and there’s a real call for public media to step up,” David Fanning, the executive producer of “Frontline,” said in a telephone interview before the announcement. “The summer hiatus did stop us from doing certain stories,” he added.

The new episodes, interspersed throughout the year, will include three stories an hour, not the usual hourlong “Frontline” investigations. “With shorter pieces, you don’t have the high bar of having to justify a full budget,” Mr. Fanning said.
