See some of NPR's best-known voices in the flesh, including hosts Robert Siegel, Michele Norris, and Melissa Block, and watch NPR's first and most famous program in the making!

At 5 p.m. EDT on May 3, 1971, the first edition of All Things Considered went on the air. In the more than three decades since, almost everything about the program has changed -- the hosts and producers, the length of the program, the equipment used, even the audience. But one thing remains the same: the determination to get the day's big stories on the air, and to bring them alive through sound and voice.

For two hours every weekday, All Things Considered hosts Robert Siegel, Michele Norris and Melissa Block present the program's trademark mix of news, interviews, commentaries, reviews and offbeat features.

The program rings with the disparate voices of its commentators, from veteran analyst Daniel Schorr and storyteller Kevin Kling to poet Andrei Codrescu. It hums with the distinctive music that threads between reports -- music collected in the online program All Songs Considered. And by the time All Things Considered marked its 30th anniversary on the air, the program had earned many of journalism's highest honors, including the Peabody, duPont and Overseas Press Club awards.

In 1977, All Things Considered expanded to seven days a week with one-hour news magazines Saturday and Sunday evenings.
