The "Beta Series" refers to a classification of television shows that are in the testing phase before their official release. These shows are often produced to gauge audience interest and gather feedback, allowing networks to make adjustments before a full season is aired. The term "beta" is borrowed from software development, where it indicates a version that is still being refined. In the context of television, a Beta Series may include pilot episodes or limited runs that showcase new concepts or characters. This approach helps networks like NBC, ABC, or Netflix determine which shows have the potential to become successful long-term series based on viewer reactions.
