After years of refusing to entertain the idea of selling its long-struggling TV business, Sony Corp. CEO Kazuo Hirai said Wednesday that putting the unit on the auction block is now an option.

"It's not that we aren't thinking about partnering or selling to other firms at all. . . . Depending on the situation, we'll have to consider (such options)," Hirai said at a news conference at Sony's Tokyo headquarters during which he introduced a new three-year business plan.

Previously, Hirai had said that the TV business was important to the electronics giant and that he was not thinking about selling it.
