Argentina's broadcast media regulator has new rules for television news: From now own, subtitles must be added to video showing where and when it was recorded.

Audiovisual authority President Martin Sabbatella says failure to identify the place and time of events shown on TV news "is especially serious when it involves violence, protests, tragedies or problems in public spaces." He says viewers should know if the trouble is happening now where they live, or is already over somewhere else.

The new rules require old news video to be clearly labeled "archive." Live shots must identify the location, and video recorded earlier the same day must include the hour.

Free press advocate Claudio Paolillo has no problem with the new rules. He says clearly identifying content is simply good journalism.
