CBS has pulled the plug on its revival of Murphy Brown after 13 episodes, opting not to bring the resurrected series back for a second season. In the last few years, TV has seen an explosion in the amount of reboots, sequels, revivals, and spinoffs of existing popular shows. While Hollywood has always loved expanding franchises, the uptick as of late on the small screen has been very noticeable, with sitcoms like Arrested Development, Will & Grace, Roseanne, and Full House all getting second chances at life.
