Federal Communications Commission Chairman Reed Hundt wants to make all non-cable television stations air at least three hours ofeducational programming for childrenevery week. "The TV is the third parent in most households," said Hunt, whose plan (to be formally unveiled tomorrow) would gradually increase the quota to five hours. Broadcasters could trade the obligation with other stations, as long as they advertised the shows so parents would know where to find them. Two FCC commissioners contend the Hunt proposal would violate First Amendment rights. Stations already are required to air children's programming, although the hours are not specified and some fill the time with cartoons.TIME Washington economics correspondent Suneel Ratansays Hunt's plan is likely to face opposition from Congress, which is "not exactly in a pro-regulatory mood."
