The show was originally developed for ABC, but the network executives didn't know what to do with it so they turned over the rights to the producers, who then sold it to HBO.

The 1988 Writers Guild of America strike adversely affected the show, which only shot a few special episodes that year.

Audrie Neenan (Jacqueline Pennell) quit the show when she was offered a role in the female cop pilot Fraud Squad (1985), which never became a weekly series. On-screen, it was implied that the missing Ms. Pennell had been murdered by anchorman Bob Charles.

Danny Breen was initially unhappy on the show, so the producers decided to give his character the worst assignments ever. "Everything started to click after that," he remarked in a 1985 interview with the Virginia Times-Herald.

Rich Hall left in 1984 to star in Saturday Night Live (1975), but he only remained on that show for one season. He gradually returned to NNTN, first making guest-star appearances before he was reinstated as a regular cast member.

One of the only successful American pilots of all time. This is a remake of not the 9 o clock news.

Most seasons featured one episode per month, plus some additional specials sporadically. In 1989, the show was drastically overhauled and aired weekly, with "live" episodes which were actually taped on the day that they premiered so they could include up-to-date humor.
