The worlds we create for ourselves seem to turn slowly most days, and then one day the future arrives with full force.That force hit last week at The Oregonian, where I worked for more than two decades, with the newspaper’s announcement that it was laying off an undisclosed number of employees and cutting home delivery to four days a week.The announcement was sudden, kept secret even from top newsroom managers, I’m told. But it had been coming for years as the newspaper’s corporate owners, New Jersey-based Advance Publications, tested non-daily deliveries and even non-daily publication in New Orleans, Birmingham and Ann Arbor, Mich. So no one who works at the newspaper could say they were surprised that it came to this.At a gathering in a Portland bar Thursday night, journalists had counted more than two dozen of their colleagues as having received pink slips. By Friday, the number reportedly had reached 35. The list included some of The Oregonian’s best journalists, including one married couple and many in their 50s and 60s — hardly an optimal age to be reentering the job market.Those remaining will face new marching orders to push their work more quickly onto the company’s website, and they’ll deal with the euphemisms of a corporate mind-set in which the job title of editor is replaced by “managing producer.” (The Columbian will continue daily publication and home delivery, although publisher Scott Campbell says he hasn’t ruled out possible changes in the future.)It’s beyond debate that the newspaper industry needs to adapt, and quickly, to technologies that offer a treasure trove of information about every topic and from every viewpoint. The industry has been slow to change, in part, because most of its revenue comes from print advertising and subscriptions.
