Time Warner Cable and Cox Communications denied a Wall Street Journal report on Monday that Time Warner Cable had approached Cox Communications to discuss a potential merger.
Cox Communications "did not show interest" in the discussions, the Journal reported, citing people familiar with the matter.
"It's simply not true. We have not engaged in any discussions with Cox," Time Warner Cable's spokeswoman Susan Leepson told Reuters.

A spokesperson for Cox Communications also said that the company was definitely not for sale.
