Attack of the Show
As G4 finalizes plans for a channel makeover in 2013, the young male-skewing network will conclude the runs of its two signature series, Attack of the Show and X-Play. Both long-running shows will wrap up production at the end of this year.
Attack of the Show and X-Play will continue to roll out new episodes through December. Leading up to their finales, a rotating lineup of guest co-hosts will join Attack of the Show hosts Candace Bailey and Sara Underwood, including John Barrowman, Michael Ian Black, Josh Myers, Paul Scheer, Rob Huebel and Horatio Sanz. Various stars are also expected to join X-Play hosts Morgan Webb and Blair Herter on their show.
