TVI was launched as 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. Quatro's launch identity was made by Lambie-Nairn.
Used only in idents. TVI used their old logo as their channel bug until February 1995 and also at start-up and closedown.
TVI's logo was changed in 1995, in occasion of its second anniversary.
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 "tvi" wordmark on the right side.
On February 20, 2014, on its 21st anniversary, TVI renewed its image as well all the channel idents, but keeping the format of the previous logo. Despite the new logo, TVI still uses the old logo at times.
On TVI's 24th anniversary, they launched a completely new logo in line with its thematic channels. The new logo which replaces the one used since 2000, has the TVI letters joined together and with colors below highlighted by a slanted line. While the symbol used since 2000 was discarded, it still appears in TVI's idents (until 2020) and its colors of red, yellow, and blue, albeit in different shades, continue to live on as the colors highlighted by the slanted line below.
