NEW YORK (AP) — At the show’s inception in the mid-1970s, the cast of NBC’s “Saturday Night Live” was known as the “Not Ready for Prime Time Players.” That now seems bitterly ironic for the network.

The final numbers aren’t in yet, but last weekend’s “Saturday Night Live” with Justin Timberlake as host had far more viewers than anything NBC aired in prime time last week. The badly slumping NBC had its lowest prime-time viewership average ever, even counting summer months, the Nielsen company said.
