Thanks for posting these Noticiero Eco clips. Kudos to you. I'm sure these haven't been on this forum before. So am I.
Clearly the first clip was taken from a tribute program of a long-running Televisa anchor, minus the lower third graphics or watermarks.
Anyway the earliest clips of Eco that we found are from the 1990s on TV Ark (under the Other Channels section; back in the late 2000s) and some are on Youtube. TV Ark was one of the earliest TV presentation sites that I visited, long before I found TV Forum in late 2012.
The reason Eco was on the Other Channels section on TV Ark is Eco was aired across Europe via satellite. I think ironically it carried the Galavision watermark (from what I saw on Astra TV channel surfing videos from the 1990s), although I presume Eco in Europe carried no other Televisa programming other than Eco. Never think of Eco being carried outside America and Europe.
When I watch the clips, I found the headline part and the opener part very tedious.

Because they're very long in duration, unlike other news channels. What I think in hindsight right now is Mexicans are used to have a laidback presentation. Yet when I watch the first clip that you share, I was surprised that they continue to use the same theme music later in the 1990s.
Back then I had minor interest in Spanish-language television. But I know some of the news openers and idents from the various Spanish-speaking countries like Chile, Colombia, Venezuela and Argentina. Now I've been progressively interested in Spanish and Portuguese again since last year.
Anyway the Mexican 24 Horas and Eco has been long defunct. But you would like to know that there are some Spanish news channels that exist today like CNN en Espanol, CNN Chile, Todo Noticias and Canal 24 horas (the other one from Chile). I think you know the former two.
BTW honestly I've never seen any Televisa news openers other than the idents of Televisa stations. Maybe because back then I was too lazy and had lack of interest to learn Spanish.
PS: It's odd to see how Spanish-speakers to use various variations of the word "noticias" such as noticiero, noti, and noticiario (the latter might be formal).
