NickJr.com has launched a sneak peeks video platform meant to draw users to the network's larger broadband re-launch that will make available full-length episodes of shows such as Dora the Explorer, reports AdAge (via MediaBuyerPlanner). Though ads on that section of the site, Nick Jr. Playtime, are geared toward the adults (mostly moms) helping children navigate, the navigation itself is geared toward preschoolers.

"We're seeing two-year-olds on the web with their parents," said Kyra Reppen, VP and general manager of NickJr.com. The Playtime area of the site is where "we've committed to creating preschool usability and navigation."

This is the second launch for Nick Jr. Video, which introduced the broadband-based Nick Jr. Parent's TV about a month ago.

Separately this week, Nickelodeon is expanding Nick.com with the launch of NickMail Maker, an instant messaging platform it's calling a "hybrid of email, instant messenger and animation applications."
