PBS has been known to push the envelope with some shows. In 1999, an episode of "Frontline" aired containing the f-word, along with other strong language, and suggestive content. Only private parts were censored. That episode should've been rated TV-MA; an edited version could've received a TV-PG, but even that is pushing the envelope. New episodes are very tame compared to that 1999 episode and cover a wide variety of topics including the war in Iraq and the media industry. I highly recommend this for anyone interested in current events, though most teens won't watch unless it's for school.
