On March 20 , 2009 , '' SmackDown '' celebrated its 500th episode . On September 15 , 2009 , WWE Home Video released a DVD set entitled '' The Best of SmackDown 10th Anniversary '' . The '' SmackDown '' 10th Anniversary DVD which included the Top 100 moments in '' SmackDown '' history was hosted by Cole and Matt Striker . On April 19 , 2010 , the eruption of a volcano in Iceland left ash hovering over Europe and caused the grounding of many flights , leaving most of the '' Raw '' roster stranded in Belfast , Northern Ireland . To keep the audience from thinking that '' Raw '' was canceled for the night , '' SmackDown '' wrestlers ( including Rey Mysterio , Edge , CM Punk , Chris Jericho ) took over '' Raw '' . The episode is known as '' Monday Night SmackDown '' , although that title was never mentioned on air . On October 30 , 2009 , Todd Grisham was revealed as the new lead announcer for '' SmackDown '' , alongside Michael Cole for one night on October 16 , 2009 , and Matt Striker , a position he held until December 3 , 2010 , when he left to become the new lead announcer for '' NXT '' along with Josh Mathews
