Walt Disney CEO Bob Iger is still bullish on ABC.

"ABC is still an important business for us," Iger told CNBC's "Squawk Box." "It's very healthy content creation business. Whether you are talking about the programming that we own and produce in prime time or ABC News, it's a profitable business. It's a business that we are proud to be in, and it's still in my heart."

Of course Iger has close ties to the TV side of the business. Before ascending the corporate ranks at Disney, Iger was chairman of the ABC Group and oversaw the broadcast television and station group.

He started at ABC in 1974, and his skill took him to the top of that network.

But Joe Kernen of "Squawk Box" responded by saying of ABC: "Shrinking, though, isn't it?"

Iger, however, still defended ABC. "Well, if you look at the size of the company, because the company has grown, particularly given the acquisitions and growth in international markets, you know, there are a few of our businesses that don't loom as large as they once did," Iger said. "But that doesn't mean they're not important."

ABC was the only major broadcast network up with the 18-to-49 age group last season. The network had new hits last fall with "How to Get Away With Murder" and "black-ish."

In news, "Good Morning America" remains the leader in early morning, and "ABC World News Tonight With David Muir" has grown this season. Diane Sawyer's interview with the future Caitlyn Jenner underscored that network news can still draw viewers.
