I watched all five hours of both the LIV Golf and PGA Tour telecasts today, thanks to setting up two TVs side-by-side. I took a few notes on commercials. The LIV telecast had about 45 minutes of breaks. I didn't notice any national ads, though there were plenty of CW Network promos, including one for their other sports offering, a documentary series on the road to the Indy 500 starting in March. There were plenty of local ads on WGN Chicago, plus a few promos for WGN shows and the NewsNation, which runs on WGN America (and which might have run on the CW network, for that matter).
I didn't specifically chart golf shot frequency on the two telecasts, but there did seem to be more on the LIV show. The move by CBS and NBC to rely on Trackman-type graphics for tee shots seems to lead to longer set-ups for a shot. LIV uses those too but gets to the shot faster (and on one hole had an interesting dispersion-pattern graphic for the shots). Both had plenty of aerials and beauty shots.
I only listened to the LIV show. David Feherty seemed in good form, Arlo White anchored well enough, and Jerry Foltz and the on-course folks, also holdovers from last year, still aren't interesting. At least there was less "this is the greatest innovation in golf" tail-kissing than before.
