Brian Steinberg Senior TV Editor “Night Court,” the NBC sitcom that was recently rebooted, enjoyed its heyday after its debut on NBC’s Thursday-night schedule in 1984. But NBCUniversal is hoping the retooled comedy will lead Madison Avenue into the future. When the original program launched, built around star Harry Anderson as a non-traditional metropolitan judge, NBC sold ads against the debut broadcast of each episode as well as a rerun later in the season. Now, says Mark Marshall, the executive recently given wider oversight over NBCUniversal’s national ad sales, the company is selling broad-reach ads attached to the linear debut of each episode as well as targeted advertising that appears adjacent to the series when it streams on Peacock.
