Time Warner's HBO has one of the most popular shows on television, "Game of Thrones." HBO Time Warner just turned down an offer valued at $80 billion from 21st Century Fox to acquire the company.

A merger of the two companies would create a massive media empire.

If the two were two join forces, what properties would fall under the same umbrella?

Among Time Warner's properties are one of the top movie studios, Warner Bros., premium content network HBO, and Turner Broadcasting System.

21st Century Fox already has a movie studio of its own, along with Fox and its many sports channels, National Geographics networks, and FX.

For a complete list, we turn to Columbia Journalism Review's Who Owns What guide.
