These days, the new Discovery slate has seen marked improvement, kidwise, across the board.

The three-hour Saturday a.m. block consists of half-hour skeins “Prehistoric Planet,” “Croc Files,” “Operation Junkyard,” “Endurance,” “Scouts Safari” and “Strange Days at Blake Holsey High.”

Season to date, the rating among kids 2-11 is up 40%, while the key boys 6-11 demo has increased by 75%.

But those aren’t the only numbers on the rise. Despite the targeting of kids with the new programming block, NBC’s Saturday morning median age has creeped up to 41.7. Adults 65+ make up 19% of the block’s audience, up 6% from last year. Kids 2-11 compose 13%.

This makes the Peacock’s viewers significantly older than the competish. Top-rated nets Nick (9.8), Kids WB (12.4) and ABC Family (12.6) all hit their target audience. But Discovery’s (perhaps appropriately named) “Prehistoric Planet” show pulls in a median viewing age of 50.6. By comparison, the median age tuning into top-rated “SpongeBob Squarepants” on Nick is 10.
