Still stinging from Boobygate, MTV which produced Janet Jackson's Super Bowl snafu is toning down its racy content. That means six spicy videos, including Britney's "Toxic," are moving from daytime rotation to the overnight period from 10 pm to 6 am. Is the network censoring itself? "Given the particular sensitivity in the culture right now," an MTV spokeswoman says, "we're erring on the side of caution for the immediate future." Other music acts bumped into night-owl rotation include Blink 182, Maroon 5 and Incubus.
