First up, TV1. TV1 changes its presentation line-up, made a new ident and adds a new slogan called "Mewarnaimu" (Colours you). TV1 lacks a slogan since its logo change in January 2011. This happened by the start of February.
Second, TV2. By the start of this week on Monday, TV2 made a minor change in its logo design. The box behind the number 2 on its logo has been removed. The revised logo is currently used only for its top-right logo generator appearing during programmes and its promos. TV2 still uses the previous logo design for its ident and break bumper. TV2's current logo, which has been used since January 2009, had a minor logo design change in January 2011. TV2's logo is similar to TV1's previous logo.
The next day, the old logo design which appear during programmes in the top-right has been changed to the 3D cake one. Even the programme name and the colour on the left side which appears on the top-left has been changed to just green for all programmes, instead of purple for general programming, yellow for children's (but I've seen it appearing again today) and green for Islamic programming.
TV9 also stopped using themed idents that appear on certain times of the day and the second ident and "now, next" information that appear before the end of each commercial break. Instead, programme block idents (which have TV9's new logo design at the end) and break bumpers will appear on certain programme blocks such as Mutiara Hati and Raudhah. No changes for Bananana, which is a children's programme block with the block also used by TV3, NTV7 and 8TV. Even TV9's slogan is gone. TV9's previous slogan is "Dekat di hati" (Close to the heart) and later just "di hatiku" (at my heart).
Of all the TV logo changes that I have seen, TV9 has the most apparent logo design change.
