PITTSBURGH - Pitt is back.

The University of Pittsburgh's athletic program Thursday unveiled a new logo for its 19 intercollegiate sports teams that might look familiar. The block-letter, navy blue and gold "Pitt" is reminiscent of the logo the Panthers wore as early as the 1920s.

The new logo means the school is embracing the Pitt nickname again.

The school's teams had a script-letter Pitt logo from 1973 to 1996. In 1997, the school began using "Pittsburgh" on its uniforms and logos.

"Even when it was de-emphasized, the Pitt moniker never left the consciousness of our fans," Athletic Director Jeff Long said in a statement. "I recall saying upon my appointment as athletic director that I believe there are appropriate times to be recognized as 'University of Pittsburgh' and other times when we want to be recognized as 'Pitt.'"
