An animated prequel to the live-action show "Sabrina, the Teenage Witch," the series features 12-year-old Sabrina Spellman, who's half mortal and half witch. Though few people know of her powers, and her mortal uncle frequently warns her not to use her magic to solve problems, Sabrina still borrows spells from the Spookie Jar and gets into trouble with her friend Harvey. Star Emily Hart is joined by Nick Bakay, also the voice of Salem in the live-action show, and her older sister, Melissa Joan Hart, here playing Aunt Hilda, though she played the title character in the live-action version.

The "Peanuts" comic strip was a staple of daily life for many Americans for nearly 50 years until original production ended in 2000. Now, the classic cartoons are coming to life -- in animated form at least -- in this series. The show uses a pen-and-ink animation style along with textured backgrounds and framing to emulate the look of the original strips as they appeared in newspapers. "Peanuts" aims to bring the classic adventures of Charlie Brown, Snoopy, Lucy, Linus and the rest of the gang to a new generation that is more familiar with 2015's computer-animated "The Peanuts Movie" than the original comics.
