1968-1977 By the time of the start of RTP2's broadcast, it didn't use any logo but has used the same logo as its sister channel RTP1.
1977-1979 RTP2 began a 12-year period of changing logos alongside its sister channel RTP1, and that's why these two channels were changing their logos as well as their on-air identities at overall for a lot of various times. Obviously, RTP2 were adopting a new logo as a separate entity in October 1977, and it were consisting of a stylish-lowercased
rtp wordmark alongside the 2-numeral that is formed out of the letter
t, because this logo is so famous for appearing on
Zé Gato, that had been aired on RTP2.
1979-1981 Sometimes when RTP's two TV channels commenced a 5-year period of sharing their same logo format with some different colors, RTP2 began to use a new logo on 14 June 1979, and eventually, its new logo were the same than RTP1's new logo, but the
RTP1 wordmark are instead replaced with the
RTP2 wordmark, because this logo is colored with yellow, so that's why yellow will be RTP2's favorite color.
1981-March 1983 In February 1981, RTP2 got a new logo again and it were the same than RTP1's logo, but the 1-numeral are instead replaced with a red 2-numeral, especially that the
RTP wordmark are appearing under the 2-numeral although it is also colored with red.
March–July 1983 Later, on 21 March 1983, RTP2 adopted another new logo which is same than RTP1's new logo, and by that, this new logo came up with an
ident that contains some music which is a crescendoing synthesizer tune that is sounding very similar to THX's
Deep Note.
July–October 1983 October 1983-1984 1984-1985 In the spring of 1984, RTP2 were launching yet another new logo that is similar to RTP1's new logo, but eventually, the 1-numeral are still again replaced by the 2-numeral while it is beside to the "RTP" wordmark, although it is using the Sinaloa typeface while appearing inside a rectangle.
1985-1986 From December 1985, RTP2 got a new logo that consists of a red 2-numeral that is drawn out of three lines while the
RTP wordmark are colored with royal blue although it is underneath the symbol, but the
RTP wordmark were soon adopted on RTP's logo within the following year.
1986-1988 On 13 October 1986, RTP2 were again getting another new logo that gets changed into a rounded rectangle which has the
RTP wordmark appearing to the left of the side of the 2-numeral.
1988-1990 On 2 December 1988, RTP2 were yet again relaunching its on-air identity with a new logo that consists of a 2-numeral which is formed up of three lines that is colored red, green, and purple, although they are forming a larger 2-numeral which will contain a picture that can be seen from the transitory phase which will lead into RTP2's next on-air identity.
1990-1992 On 17 September 1990, RTP2 introduced a new logo which consists of a 2-numeral that is supposed to be a permanent, white and opaque
DOG, although it depicts a handwritten "2"-numeral, and it were eventually coming up with some idents that consists of mainly on several fruit chopped in the middle by the logo, though it gets accompanied by synthesized pieces of music, and besides, there is also a startup ident which consists of something for what it should look like a chalkboard that is drawing of a line which will enter into a TV set until it later forms the logo, but there is also a closedown ident which consist of an animation with the same style that has been used for why it is focusing on the Portuguese discoveries, and that's how it were used as RTP2's anthem film during its on-air identity.
1992-1995 Later, on 14 September 1992, RTP2 became rebranded as
RTP TV2, and by that, it introduced a new logo which is based on a stylized yellow-colored stripe that is forming a "2"-numeral, while it is beside to two pieces of
quartz that is forming the word "TV", and however, this logo came up with some various idents that are featuring at that time some prominently yellow stripes. The logo was designed by Monika Cabral, a Brazilian working for the Portuguese arm of
Young & Rubicam, and was the result of a competition at with sixty entries, which were shortlisted to the three best. The designer took three weeks to conceive it. In 1994, the graphics were slightly changing to a yellow background with some various stripes, but the logo were remaining the same.
1995-2001 On 29 April 1996, to coincide with the implementing of RTP's new corporate logo, RTP TV2 decided to revive its original name, and so, it were reverting its name back to its original brand as
RTP2, thus getting a new logo which consists of a white "2"-numeral that is inside a light-orange-colored background along with the "RTP" wordmark which is underneath in white color, although it is overlaid in a dark blue background, as RTP2's new-looking idents are consisting of mainly on the logo that is flashed on several themes such as
typewriters, stripes (a reference to the previous identity), and some dancing people, although these idents are getting accompanied by RTP2's orchestral tune with some prominent arrangements of a
harp,
violin and
cello. On 12 October 1998, RTP2 redesigned its 1996 identity with a new look that is designed by Thomas Sabel at Novocom, and it will especially give an predominance to the actual people by adding the green color into its color scheme, and besides, from 2000, they were later changed into simple-looking graphics that are designed by
BBC Broadcast, but these graphics were only used for promos and the 1998 idents continued to be used. The 2000 graphics were short-lived because they are lasting a short use until 2002 when RTP2 updated and got a new logo.
2001-2004 On 28 January 2002, RTP2 were again upgrading a new logo alongside its sister channel RTP1, but this identity are only using one single ident that is used during the lifetime of this logo, and it consists of a representation of RTP2's logo in a white flash, with a dark orange background.
2004-2007 On 5 January 2004 at 21:00, RTP2 dropped its
RTP2 brand changed its name to "2:", also changing its identity, aiming for a younger, yet general audience. All of its bumpers were generated with
CGI, and the sound consisted of a lot of electronic and classical sounding music, with prominent piano arrangements.
2007-2016 On 19 March 2007, 2: retired its "2:" brand, and by that, it were reverting its channel name back to the original name as RTP2, thus reviving the "RTP2" brand, but at the same time for resurrecting the RTP2's original name, it implemented a new logo by adopting some new idents that continues to become computer-generated CGIs with a lot of vertical stripes in their various forms as the main theme. The rebrand cost €150,000. ==Criticism==
