Teenage Thunder

Teenage Thunder was released in late 1957 and originally registered for copyright by Howco Productions, Inc. on December 27, 1957 (Registration Number LP10926). Under the Copyright Act of 1909, works registered between 1928 and 1963 required a manual renewal filing with the Copyright Office during the 28th year of the first term to maintain protection for a second term. For a 1957 registration, the renewal window was open in 1984 or 1985. A search of the Stanford Copyright Renewal Database and the U.S. Copyright Office online records confirms that no renewal was filed for this motion picture. While many Howco titles from this era (such as those involving Roger Corman) were occasionally renewed or transferred, Teenage Thunder was not among them. The film has subsequently appeared in numerous 'public domain' DVD collections from labels like Alpha Video and Mill Creek, and it is hosted as a public domain work on the Internet Archive without challenge from any successor-in-interest. Therefore, the copyright expired at the end of its first 28-year term in 1985.
