Television viewers — even those who watch the more sober-minded PBS — are generally not keen on sitting through long speeches. But TED, the nonprofit group that sponsors conferences on ideas, thinks it has found a way to bring its signature 18-minute talks to a TV audience that may not have found them on the Web or through mobile apps.

In its first television foray, TED has joined forces with the Corporation for Public Broadcasting and the New York public broadcaster WNET for a one-hour special, “TED Talks Education,” to be broadcast on PBS on Tuesday. If it is successful, the program could become a template for future joint projects, said Juliet Blake, one of the show’s executive producers and the TED official charged with bringing the conferences to television.

The program was 18 months in the making, a short time for public broadcasting but long for TED, which is accustomed to the more immediate online world. Other suitors have also sought to do TED television projects, Ms. Blake said, but “to reach the audience we want to reach, public television was the place.”

The Corporation for Public Broadcasting paid for the show’s $1 million costs under the auspices of an initiative that addresses the high school drop-out problem in the United States. “It was the perfect marriage of ideas that matter and our core value of education,” said Patricia Harrison, the corporation’s chief executive.
