The No. 1 cable company will flood its on-demand menu with children’s shows in July — part of an effort to demonstrate to parents that they don’t have to buy a streaming service from Netflix or Amazon to find programming that will keep kids occupied in front of the TV or a mobile device. The “Summer Of Kids” plan follows Comcast’s “Watchathon” event in March that highlighted the virtues of on-demand. In the new campaign, Comcast says it will offer content from “every major kids network and brand,” including more than 1,000 downloadable TV shows and films. In conjunction with the “Summer Of Kids” campaign, Comcast is introducing guides in collaboration with Common Sense Media to help families find age-appropriate fare. That should give parents “ultimate peace of mind for safer, smarter viewing across devices,” says Comcast Cable’s programming VP Maggie Suniewick. For the last two weeks of July the company will open its public WiFi hotspots to anyone, not just subscribers, although only Comcast customers can access the “Summer Of Kids” content. Shows to be showcased include Dora the Explorer, Angry Birds Toons, Sofia the First, Phineas and Ferb, Ben 10, Mickey Mouse Clubhouse, The Chica Show, Sid the Science Kid, Lazy Town, Pajanimals, My Little Pony: Friendship Is Magic.
