IMSA has made massive changes to TV coverage, most notably getting rid of Bob Varsha and Justin Bell, moving to a two-man team of Calvin Fish and Greg Creamer with Fish as the lead, Brian Till being the only pit reporter. IMSA will now have primary control over the content aired, basically becoming the director (assuming this is like F1 and WEC with the world feeds). This all stems from the shitty ratings FOX got in 2015. IMO, the TV team wasn’t the issue, the issue was FOX’s production of the race with to the continuous commercials (I get that ads fund the broadcast but even NASCAR coverage didn’t have this many commercials) and the constant switching between FS1, FS2, the utterly useless FSGO, and IMSA TV.
