Peter Scheer (pictured), executive director of the California First Amendment Coalition, has come up with an idea that might save the newspaper business. In a commentary posted on the CFAC Web site, he suggests that newspapers keep news stories off of their free Web sites for 24 hours in order to make their print (and paid Web) editions more valuable. A few years ago, newspaper executives who were trying to develop their Web sites might have scoffed at such an idea. But now that newspapers have discovered that they won’t be able to replace most of the revenue they got from print ads with Internet ads, this idea might fly. After Scheer posted this commentary on his site, the Chronicle ran it as an op-ed on Sunday.
