Spin-Off Silver Age
The Spin-Off Silver Age was the second era of spin-offs that began when The SpongeBob Community broke away from the TV.com SpongeBob boards. It lasted from 2009 to 2011 and featured the evolution of spin-offs in form factor, going from a paragraph or two to full-length episodes. This revolution was led largely by that70sguy92, who defined the era with a series of hit shows, including Bikini Top, Hitting Rock Bottom, and The Guitar Lord. The Silver Age was followed by the Aluminum Age.
