It’s party time at ABC News. The final Nielsen numbers are in and “Good Morning America” will win its first week in Total Viewers since 1995. And to celebrate, ABC News president Ben Sherwood is calling an all-staff celebration this morning.

“It’s official!” writes Sherwood in a memo to staff this morning. “‘Good Morning America’ won last week by 31K total viewers, breaking Today’s historic streak.”

At 11 a.m., please join the GMA anchors and staff in the newsroom on the fifth (5th) floor for a toast to this great team and achievement … 852 weeks in the making. It’s a very special day for ABC News. Congratulations to each and every one of you!

Monday’s preliminary numbers put the weekly win at 13,000, but widened to 31,000 with the final results. We’ll have the regular weekly ratings post later this morning.
