After 142 years, the Oakland Tribune today printed its last edition. So too did the San Mateo County Times. The Trib will be replaced Tuesday morning by the East Bay Times, a consolidation of the Tribune, Contra Costa Times, the Daily Review in Hayward and The Argus in Fremont. Similarly, the San Mateo County Times will become the Mercury News. The South Bay paper is dropping “San Jose” from its name. The consolidation came with about 20 layoffs in the newsrooms of these publications. All are apart of the Bay Area News Group. Subscribers in Oakland, Fremont and Hayward will receive news inserts bearing the old dailies’ names each Friday.
