NBC

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

Throughout the 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.
