It's the most wonderful time of the year, television reminds us, and as many say, the holidays are all about the kids -- a time when families gather in the spirit of the season to renew ties, exchange gifts and reminisce about the good ol' days. At least in most cases. In some families, the gathering is a reminder that the children's growing-up years were filled with TV cameras capturing their magic moments merely for the edification of an entertainment-starved public and/or a healthy hunk of money. As we sit back and imagine future family gatherings of the 'Jon & Kate Plus 8' clan and their therapists, lawyers and court-appointed guardians, let us look back at some of the other most child and teen-exploiting shows in the history of the tube.
