"The contractual issue just never worked out, but I was going to leave before that anyway," Philbin said on Detroit's "Mojo in the Morning" radio show Friday.
Philbin, who has co-hosted the daytime talk show for more than 28 years, expressed that ABC was making a mistake in letting him go. "Of course it's a big mistake, but Regis is moving on," he said.
In January, Philbin announced his exit. "There is a time that everything must come to an end for certain people on camera," he said then, joking, "especially certain old people." His last day will be November 18.
