Exec producer Jay Daniel is leaving Carsey-Werner Co.’s “Roseanne” after a four-year affiliation with the series.

The company confirmed his exit after full-page ads were taken out Friday by exec producers Roseanne and Tom Arnold thanking Daniel, who’ll turn his attention to developing a new Carsey-Werner series.

A C-W spokesman said the change had been planned for some time and that Daniel will remain a consultant on “Roseanne.”

Formerly the producer of “Moonlighting,” Daniel joined the series in January 1990 to smooth tensions between the show’s star and then-exec producer Jeff Harris; Harris subsequently left, placing his own ad saying he was opting for a vacation “in the relative peace and quiet of Beirut.”

Daniel, in fact, has been a source of stability on the high-rated sitcom, which has undergone near-annual exec producer turnover dating back to its 1988 premiere. Most recently, Bob Myer left after the 1991 season for an overall deal with ABC Prods., and Bruce Helford and supervising producer Bruce Rasmussen exited last year, with Rob Ulin elevated to co-exec producer and head writer.

The Arnolds have said in interviews that they feel it’s necessary to keep bringing new writers aboard in order to maintain the show’s quality.
