Don Buchwald, a talent agent who elevated shock-jock radio personality Howard Stern to satellite radio, died on July 22 at his home in North Egremont, MA. He was 88.

In late 1985, after WNBC fired Mr. Stern, Mr. Buchwald negotiated his move to WXRK-FM, known as K-Rock. Over the next 20 years, Mr. Stern’s popularity swelled, and his show was syndicated to stations nationwide. But it was Mr. Buchwald’s negotiating in 2004 that led to a groundbreaking five-year $500-million contract with Sirius Satellite Radio, where he could say anything he wanted, compared with traditional radio, where his sexual and scatological references led to fines by the Federal Communications Commission against stations that carried his show. The Sirius deal included 34.4 million shares of the company’s stock, which were worth $219 million, when the show made its satellite debut in early 2006.
