Stop sexual videos on TeenNix

Watching the 70's show this morning on one of the Nickelodian channels, I was appauled to see that every 10-15 minutes there was a music video with guys and girls being extremely sexual toward each other: one guy with lots of girls kissing and almost making out with their movements; others dancing in such a sexual way that they might as well had been making out.  This is inappropriate for this channel.  It almost promotes teenage sexuality.  What has happened to Nickelodian?
