The ABS and CBN acronyms merged below, forming the unified name ABS-CBN, and was given a more refined version of its typeface. The three rings and vertical line remain, but the outlined black box encasing them was removed and replaced by a grey square.

While the overall design remains unchanged, the typeface of the name has been simplified by removing the serifs, the rings and vertical line are drawn thicker, and the grey square is replaced with a white square.
