Found the Rare VHS Recordable Tapes and/or DVD Recordable Discs from Garage Sales, Thrift Store, and more local retailers other shows from Univision from 80s, 90s, 2000s, and 2010s Graphics from Univision O&O and Entravision
Since you're good at finding rare Univision stuff, I wonder if you can find video or videos on Youtube that has this audio source: http://www.southernmedia-nmsa.com/#1,1,WXTV (1990 WXTV News Theme, first audio track says it's from 1993 sometime ago before the name change) I'll subscribe to your Youtube channel if you found it.
Anyways, currently the Univision affiliated stations are still using the 2013 logos at least for the news graphics package. I'm expecting for the new IDs to roll out soon. I'm pretty sure a new graphics package is coming out soon.
This article confirms that the 2013 news package for the local Univision affiliates will be phaised out later this year and will be replaced by a new modern look this summer. My bets the new graphics package will be rolling out on June.
Get ready Edgar! Univision has begun rolling out the new 2019 Noticias Univision graphics package and my station, WXTV has become the very first station to utilize it since they just debuted a new set.
