Tenay would move up to Monday Nitro and would be able to fully put on display his vast knowledge of the wrestling business, wrestling history, and maneuvers getting the nickname of the "Professor" from his knowledge. Following the debut of Thunder after seeing the announce team pull double duties the company chose to switch things up. Tenay would become the lead announcer of WCW Thunder alongside of Larry Zbyzsko after the change. The change would be short lived though as the company would bring Tony Schiavone back to Thunder in December.
Following the closure of WCW in 2001, it was a while before we saw Mike Tenay back in the booth for a wrestling program. Upon the arrival of NWA-TNA it wasn't long before Mike would join the booth to become the lead announcer for the company. To start Mike would click with color commentator Don West who he would partner with for years until he was replaced by Tazz. The one constant through the years even with all the ups and downs that TNA has gone through over the years until he was relieved of his duties and moved back into a different role with the company.
When Impact made the change from Spike to Destination America they would give the company a fresh voice in the announce booth with Josh Matthews taking over the lead announce duties. In 2016 while appearing on the Ross Report Mike would announce that he quietly departed TNA Wrestling and is currently retired from professional wrestling. One interesting and fitting note is that Mike Tenay serves on the board of the Professional Wrestling Hall of Fame.
