Prexy had been with pay cabler for 33 years

Ross Greenburg, the president of HBO Sports for the last 11 years, is out at the pay cabler.

The driving force behind a slew of Emmys for the net’s docus, news shows and live events, Greenburg said he wasn’t renewing his current contract that was set to expire soon.

“I’ve accomplished everything I hoped for,” he told the New York Times.

Some have speculated that HBO programming toppers Richard Plepler and Michael Lombardo weren’t happy that rival pay cabler Showtime was able to acquire the May 7 pay-per-view fight between Manny Pacquiao and Shane Mosley that garnered just over a million buys. Greenburg, who called himself a big boxing fan, said he was tired of dealing with the sport’s promoters and managers.

Said Plepler and Lombardo in a joint statement: “We believe that Ross’ track record speaks for itself. He has helped redefine the sports programming genre and set an extraordinary standard of excellence in the industry. We will miss his leadership, vision, creativity and passion for sports television.”

HBO Sports has lately been working with Major League Baseball Prods. on a docu about New York Yankees shortstop Derek Jeter, who recently got his 3,000th hit.

For years HBO has made headlines in the summer with its “Hard Knocks” series, which details life inside an NFL training camp. The pay cabler is unsure they’ll have a new version this season because of the current NFL lockout.

At the Sports Emmy Awards in May, HBO took home three trophies for “Hard Knocks” as well as Emmys for the doc “Lombardi,” longtime newsmagazine show “Real Sports With Bryant Gumbel” and the inaugural “24/7 Penguins-Capitals: The Road to the Winter Classic.”

It’s unclear whether HBO might promote from within to replace Greenburg as sports topper, or if they will look outside to a network such as ESPN to find a replacement to run the division.

Greenburg had been at HBO for 33 years and replaced Seth Abraham as president of sports in 2000.
