For works created before 1989, it may be required; the courts have not ruled as to whether a copyright notice is required on works first created before the U.S. became part of the Berne Union. For works created after 1988 the answer is simple. No. A copyright symbol has not been necessary in the US since 1989. There are advantages to putting the copyright symbol or copyright notice on a work even if not required, including eliminating the "innocent infringer" defense.
