Known as "E.J.", Johnson works as the studio host for TNT's coverage of the NBA, including pregame and halftime shows, and the network's famous postgame studio show that airs after each NBA doubleheader, Inside the NBA.
He has hosted the show since 1990.

At the end of each broadcast, Ernie presents "E.J.'s Neat-O Stat of the Night," which has become a popular part of the show but is sponsored by no one, hence the sign that says "Your logo here".
This changed in May 2007 when vitaminwater stepped in as a sponsor for the segment, replaced by Panasonic's Viera line of televisions for 2008.
For the 2005–2006 season, his segments were sponsored by Intel Centrino and most recently Suzuki.
In the 2008 NBA Playoffs, his segments were presented by Geico and vitaminwater.

For all NBA-related shows, Johnson is joined by former NBA stars Kenny Smith, Charles Barkley, Shaquille O'Neal and, on occasion, Chris Webber, Grant Hill, or Reggie Miller.
In the 2012–2013 regular season he was joined by Anfernee "Penny" Hardaway and Dennis Scott while Smith and Barkley covered March Madness on CBS.

Johnson is also the host of Tuesday Fan Night on sister station NBA TV, alongside Webber and Greg Anthony.
 He is also the host and moderator of NBA TV's Open Court, a basketball-panel show featuring Johnson and a rotation of six panelists (all of whom are made up of TNT's NBA analysts) discussing various topics, ranging from the history of the NBA to the current day scene of the league.
