 For a brief period in the 2010s, MeTV aired reruns of several "NBC Mystery Movie" series (including "Columbo") as part of a daily late night block they called "The MeTV Mystery Movie".In order to comply with educational programming requirements mandated by the Federal Communications Commission's Children's Television Act on behalf of the network's affiliates, MeTV carried an hour-long block of "Green Screen Adventures" (Weigel's Chicago-based program originally meant for local viewing) on Saturday mornings and a two-hour block of the teen sitcom "Saved by the Bell" (which has long been used to meet E/I requirements, including by the original Chicago MeTV on WWME-CA prior to the national network's launch, and the TNBC block it formerly anchored) on Sunday mornings.In September 2013, MeTV began customizing its weekend morning lineup in order to allow its affiliates to choose between running both the Saturday and Sunday E/I blocks, or running the children's lineup on one weekend day and a three-hour block of classic series in place of the children's programs on the other, allowing stations to fulfill educational programming quotas by running the minimum three-hour requirement or an overall total of six hours of E/I content (this was reconfigured in January 2015 to allow stations the option of pre-empting the final two hours of the Saturday E/I block to carry only "Green Screen Adventures" and "Saved by the Bell" to reach their weekly E/I requirements).
