TVI was launched as A Quatro (despite TVI being its corporate name) in 20th February 1993, as a joint-venture between the Portuguese Catolic Church and various national and international media companies, including Rádio Renascença, Editorial Verbo, Antena 3, Compagnie Luxembourgeoise de Radiodiffusion, Sonae, Yorkshire Television and SBS Broadcasting Group.
A Quatro was relaunched as TVI in 1994.
TVI's logo was changed in 1995.
In 1996, TVI changed its logo. This time with the silver ball with the colorized "i" on it.
In September 2000, TVI gave a major change to its logo. This time the yellow "i" is with the red and blue curves that are around the i, and with the words "tvi" on the right side.
On February 20, 2014, in its 21st birthday, TVI renewed its image as well all the channel idents, but keeping the format of the previous logo. Dispite the new logo, TVI still uses the old logo at times.
