With 25 million consoles now in use, Emmy grows up. The first coast-to-coast telecast is jointly held in Gotham and L.A. niteries. Achievements in sports, news, music, editing, art direction and engineering effects gain recognition. Honors stack up for anthology series like “U.S. Steel Hour,” “Hallmark Hall of Fame” and “Studio One,” later associated with the so-called Golden Age. Alistair Cooke’s “Omnibus” takes a cultural programming award, and Reginald Rose wins for writing “Twelve Angry Men.” Over the years, frivolous stuff will be tossed occasional kudos, but there’ll be no more primetime awards to dummies. Wooden ones, anyway.
