Denver ? On the day his newspaper published its final edition, Rocky Mountain News Editor John Temple advised a gathering of Colorado journalists to focus on local news and suggested creating online content that niche audiences might pay for.

“It’s not realistic to think in this day and age that people are going to have one information source and you’re going to be it. You try, you die,” Temple told the Colorado Press Association convention on Friday.

“If you’re not experimenting, then I think you’re in trouble,” said Temple, who also held the titles of publisher and president.

The E.W. Scripps Co., which owns the News, announced Thursday that the Friday edition would be the newspaper’s last after nearly 150 years in business.

“Goodbye, Colorado,” read the headline on a 52-page commemorative edition wrapping the regular newspaper Friday. “STOP THE PRESSES,” read the front-page headline inside.
