Merging companies requires significant planning and approval from regulatory bodies like the FCC. The FCC has principles and guidelines for mergers that must be followed, including filing an application and undergoing public review and comment. Recently merged companies include AT&T/DirectTV, Charter/Time Warner Cable/Bright House, Comcast/Time Warner, Frontier/Verizon, and Gannett/Belo. The merger process involves filing an application, initial public notice, review of major transactions, public comment periods, and adherence to rules around confidential information.
