EVB1 (first era)
On 5 May, 1975, GTV rebrands to EVB1. This logo retained the "1" from the 1964 GTV Channel 1 ident. However, the first major showing of the logo was on GTV Midnight News for October 5, 1975, a day before this logo was gone on-air, which happened at 7pm of October 6 during EVB News at 6:45.
This logo has launched on October 1, 1977. On-screen, the logo is white and is on the bottom right corner for sports (sometimes on top right corner like the main) or as the main, on top right corner. It is hidden on commercial breaks, test cards (when test card appears, the logo stays for 4 seconds) and News1 program, by just vanishing. Vanishing first appeared in 1998.
EVB1 (second era)
This logo launched on the bottom right corner of the screen in 2000, and moved to top right in 2005. It was all white until 2007, when in 2007, it became a little transparent and moved to top left, and changed to 16:9 format.
This logo is the former EVB1 logo. It was revealed on April 18, 2010, when, two months later, the old white logos were replaced by these logos. The "EVB" wordmark was unchanged.
In February 1st, 2014, 6 days before the opening of the 2014 Winter Olympics, EVB unveiled new logos for the channels, to distinguish from making parodies and make the future for EVB. The logo keeps the same fonts, but the squares were removed, making the logo look different from the previous. The logo above debuts on March 3, 2014, at the start of the EVB's spring 2014 schedule.
On July 24, 2017, as EVB and GRT are merging to form GBS, this also included a rebrand of all EVB branded assets to GBS branded ones. EVB1, as all other channels, will rebrand to GBS1 on September 4, 2017.
