PITTSBURGH — Nationally, it may seem that in the seven years since Fred Rogers’s death, the legacy of America’s favorite neighbor has waned.

After all, two years ago PBS stopped offering his show, “Mister Rogers’ Neighborhood,” to its member stations every weekday, offering it just once a week, though it allowed stations to digitally stockpile them for daily viewing. Then, last year, PBS quietly stopped allowing stockpiling, meaning there are no stations showing it daily.

“Kids today just don’t know him,” said Tom Dvorak, director of broadcasting for WMVS-TV, a public television station in Milwaukee that in January stopped running its stockpiled shows.

But here in Pittsburgh, where he lived and worked most of his life, Mr. Rogers’s legacy seems assured, and not just because everyone over the age of 10 seems to have a story about meeting him. Images of him — and his trademark cardigan sweaters — seem to be everywhere, including displays at Pittsburgh International Airport, the Pittsburgh Children’s Museum and the Senator John Heinz History Center, for starters.
