(Reuters) – Privately held Cox Communications is considering bidding for Time Warner Cable either on its own or as part of a joint bid, The Wall Street Journal reported on Tuesday, citing anonymous sources. Recent media reports suggest Time Warner Cable is currently being circled by Charter Communications and top cable provider Comcast could jump into the fray with a joint bid for Time Warner Cable along with Charter. A Time Warner Cable spokeswoman did not immediately respond on Tuesday. Time Warner Cable shares jumped $5.02, or 3.8 percent, to $136.39.
