NogiBingo! ( stylized as NOGIBINGO!) is a Japanese television variety show starring Japanese idol girl group Nogizaka46. Ijily Okada, who is known for many AKB48 related show such as "AKB48 Nemōsu TV", hosted the program. The show firstly aired on July 3, 2013, as part of the variety show "Nogizaka46 x HKT48 Kanbangumi Battle!", and it became an independent show from the second season.
NogiBingo! only lasted for one season.
The context mentions a second season in the history of NogiBingo!. Perhaps the system considered there to be some uncertainty in the statement because it wasn't considering its time on "Nogizaka46 x HKT48 Kanbangumi Battle!" as part of the show's run.
