MediaWorks has been labelled "mean" after the network replaced its kid-friendly morning lineup on Four with a whole new channel.
Channel Four was rebranded over the weekend to Bravo, a partnership with American network NBC that features US reality shows such as Dance Moms, The Real Housewives Of New Jersey and Keeping Up With The Kardashians.
But parents took to Facebook yesterday morning to complain about the changes - especially the disappearance of Four's morning kids' shows.
Among the shows to disappear are Sesame Street, Fireman Sam and Thomas the Tank Engine.
"Two sad and upset girls here, and two pissed off parents," wrote one viewer on Facebook. "Whilst we can't see Sesame Street any more, we certainly know that MediaWorks and TV3 are Muppets."
