Most Likely because they are beginning transitions to new graphics already with CBS Sports. So sometime this week they may begin rollout. Because FOX O&Os rolled out there graphics this time last year (Super Bowl).
I really don't know what to think about these graphics tbh.
I mean when KMOV switches I hope the make them as modern as their current graphics
And when KPHO switches I hope they make them more modern too.
I hope this gives the FOX O&Os something like the NBC O&Os it's own icons and it's own standard template and switching over to 1 unified weather system and the main font Neue Plak
