Summary
DescriptionEnergizer Bunny commercial (1988).webm
English: The Energizer Bunny saw his debut in this late 1988 commercial as a parody of the Duracell Bunny, which first appeared in television advertising in 1973, in its "Drumming Bunny" commercial. Duracell had purportedly trademarked the drumming bunny character, but whether they had or not, said trademark had lapsed by 1988, providing Energizer an opening to create their own trademark.
While there is a copyright entry in the US Copyright Office database for "Energizer Bunny", it is from 1989 and only is listed as a "drawing", not as the commercial's video which is live-action. After more extensive research not finding a copyright registration for a 1988 listing of a short commercial film specifically, it is hereby assumed to be in the public domain.
This work is in the public domain because it was published in the United States between 1978 and March 1, 1989 without a copyright notice, and its copyright was not subsequently registered with the U.S. Copyright Office within 5 years.
Unless its author has been dead for several years, it is copyrighted in the countries or areas that do not apply the rule of the shorter term for US works, such as Canada (70 pma), Mainland China (50 pma, not Hong Kong or Macau), Germany (70 pma), Mexico (100 pma), Switzerland (70 pma), and other countries with individual treaties.
