This logo was designed by Paul Rand.
The original Paul Rand logo was slightly modified in 1988. This version of the design was presumably meant to make the logo clearer at smaller sizes (as evidenced by the thinner strokes on the letters and the short ascender on the "b"), but was also frequently used at larger ones. Some ABC affiliates, along with the ABC Family cable channel continue to use the 1962 design in their logos.
ABC approached graphic designer Paul Barnes to redesign the classic Paul Rand logo. He designed a logo that ended up unused. 
For the new television season in 2007, ABC rolled out a new identity package with a new tagline, logo and a new interpretation of their logo. The new slogan, "Start here", was presented at the upfronts in May. The slogan aims to position ABC as a multi platform brand, which can be watched on television, as well as on a computer or a mobile device.
In the new graphics package, the ABC logo would always appear in 3D as a shiny black disc. There were also multimedia icons developed were the ABC lettering was replaced symbols for mobile phones, computers, television screens and portable media players. The new design was created by Troika Design Group.
Although the logo is not being used, it is still being used on plenty of ABC affiliates' logos.
In 2013, ABC modified their 2007 logo. This logo first appeared on the all access website, featured in trailers for 2013-2014 programs. The new logo debuted on air on May 30, 2013. Designed by Loyalkaspar, it is inspired by Paul Rand's original 1962 design.
