NBC

NBC, also known as the National Broadcasting Company, is an American commercial broadcast television and radio network owned by Comcast.

Throughout the mid-1900s, they aired various shows from the Hanna-Barbera library, many of which, also made their debut on the channel.

In 1990, they passed on ...Where's Rodney? and Poochinski, two live-action pilots from Hanna-Barbera's Bedrock Productions. Both were eventually aired once in that summer.

In 1991, NBC ended their association with Hanna-Barbera when they canceled the dismal Yo, Yogi! for their live-action teen sitcoms on a Saturday morning.
