Walt Disney Co has held exploratory discussions about selling its U.S. TV network ABC to regional TV station operator Nexstar Media Group Inc, people familiar with the matter said Thursday.

The discussions come after Disney CEO Bob Iger said in July that the company could sell some of its traditional TV assets, which have struggled for years due to the rise of streaming services.

Nexstar's interest is preliminary and may not lead to any deal, one of the sources said.

Both sources requested anonymity because the matter is confidential. Nexstar and Disney did not immediately respond to requests for comment. Bloomberg News first reported the two companies were in talks about a deal for ABC.

Disney shares rose 1%, while Nexstar stock jumped nearly 6%.

Disney's ABC comprises a national television network and eight regional stations. It also has affiliation agreements with about 240 local television stations reaching almost all U.S. television households.

Nexstar has 200 owned or partner stations in 116 markets reaching over two-thirds of the U.S. population, as well as national TV networks such as CW and NewsNation. It has a market value of $5.25 billion.

Then Disney Chief Executive Michael Eisner agreed to buy Capital Cities/ABC for $19 billion in 1995.
