Online Frontline

The venerable PBS documentary show “Frontline” is celebrating its twentieth season. To mark the occasion, its producers have made over a dozen full-length episodes available online. Each episode is available in six, stamp-sized QuickTime segments — it’s not exactly the broadband future we’ve been promised since the nineties, but it’s still a feat that public television can deliver content in this way, while the major networks continue to wait for who knows what.
