3×3 was launched in 2005, initially replacing Teletrece AM.
After Teletrece AM returned to the channel in 2011, 3×3's programming schedule was moved to earlier in the morning.
Due the COVID-19 pandemic, and amid the restrictions imposed by the Government. the program was put on hiatus on late March 2020. It had a brief return during the October 27th, 2020 plebiscite.
In March 1st, 2021, 3x3 returned from it almost-one-year hiatus, and became officially linked to Teletrece in terms of branding. Its main logo uses a custom typography with the "×" sign having a "chevron" or "arrow" on the left part. An alternate logo following T13's intro pattern is used during opening and closing.
