As production delays create holes in the primetime schedule, ViacomCBS looks to fill CBS' fall lineup with series from the conglomerate's family of networks.

`Star Trek: Discovery` is being beamed into CBS' fall broadcast lineup. The sci-fi series, which is currently only available on the CBS All Access streaming service, will air its full first season on CBS starting September 24.

CBS, which unveiled a revised fall broadcast lineup Wednesday, billed the impending rollout of `Star Trek: Discovery` Season 1 as a promotional run to lead into the show's third season, which will launch October 15 exclusively on CBS All Access. Network executives followed a similar maneuver when `Star Trek: Discovery` first premiered: airing the pilot episode on CBS as a way to funnel prospective viewers to the company's new streaming service.

This decision is likely motivated by other needs. The news that `Star Trek: Discovery` will run on broadcast is likely part of CBS' efforts to fill a broadcast lineup that has been impacted by the coronavirus pandemic, which halted production on numerous shows that were slated to premiere in the fall. Some shows, such as the long-running `The Amazing Race,` will be returning despite production issues earlier in the year, but other original series from the ViacomCBS family of networks, as well as a separate acquisition, will also be airing episodes on CBS this fall.

`This is hardly a traditional fall season, but we are prepared with a strong slate of original content while our regular scripted series begin production,` CBS Entertainment president Kelly Kahl said in a statement. `Based on our current timeline, we hope to start rolling out our previously announced fall series as they become available in November.`
