Dateline NBC will air just once a week in the fall, on Saturdays at 8 p.m., but it’ll be back to two-a-week after the new year, when the football season ends.

“Sundays in January start with ‘Dateline’ at 7 p.m.,” according to TV Week.

> Also: An e-mailer asks an important question: “Will the remaining Dateline have the newsmagazine theme or only the crime story theme that’s now used for Saturday night editions?”
