Teletrece (also known as Tele13 or T13) is the flagship daily evening television news programme of Canal 13 from Chile. It has 4 main editions: Teletrece AM (in the mornings), Teletrece Tarde (in the afternoons), Teletrece Central (in the evenings) and Teletrece Noche (near midnight).
This logo was an interim one, only being used on-screen. It debuted alongside color television in Chile. Sadly, this was short-lived, as the program reverted back to the old logo after some time, and not much is known about this era. However, the following image (from the ending of one edition) was used by T13 in his 50th anniversary special, so it was rescued. Notice that Santander Chile (back then known as Banco Español-Chile) was sponsoring the program, so its logo appeared alongside Canal 13's logo.
In 2019, T13's logo became orange over a transparent background. This was the time where the overall branding became separated from the main, evening edition (which became known as T13 Central).
On February 28th 2021, T13 updated its graphics. Now, the logo is white and contained inside an orange cube. The editions now appear in this order, from top to bottom: AM, Tarde, Central, Noche and 3×3 (the latter only appearing in its own intro), and they're written in all caps instead of the lowercase letters. Another list is used for other editions: .cl (website), Móvil (website), Avance (news bulletins), A la Hora (weekend edition) and En Vivo (online Live transmission). However, the structures are the same otherwise.
On the March 11th edition, a special animation was put in place of the small T13 logo, which shows that logo making a smooth transition to the channel's logo. This effectively removes Canal 13's watermark during any news broadcasts, since that animation is used ever since. Another variant was used on the March 18th broadcasts, serving as a memorial for 8 women that were killed.
On the same day, and likely at the same hour, one of T13's competitors, 24 Horas, also introduced upgrades for its branding.
