T.A.C (The Acknowledgement Channel) is a fictitious television network from the YouTube comedy series The Lenny Leggo Show. The channel airs various reality television programs, including but not limited to "My Sick Addiction", "How well do you know your daughter?", "The Willer's Big Happy Family", and "Extreme Hairstylers". Additionally, they once aired a program special called "Caves you NEVER knew about". In which a supposed ancient cave, unopened for hundreds of years, was featured inside and out on the program. The channel was later sued after discovery that the program was fake, as there is no way the camera person could have shown the cave interior if their claims of abandonment held true.
T.A.C is a parody of the real life television network T.L.C (The Learning Channel). The channel also parodies various obviously fake reality TV shows.
