After three years of attempts, Viacom and CBS have finally merged, bringing the National Amusements-controlled companies back together for the first time since 2006.

The deal creates a combined entity valued at about $30 billion, putting it ahead of rival Fox ($21.7 billion) but still significantly behind giants like Netflix ($136 billion), Comcast ($193 billion) and Disney ($244.5 billion). Shari Redstone, the daughter of former CBS and Viacom leader Sumner Redstone and vice chair of both companies, will be chair of the combined company. Viacom chief executive Bob Bakish will be the merged company’s CEO.
