Jim Caldwell (born December 12, 1950) is an American television presenter. He began his television career as cohost of WNEW-TV's PM Magazine in New York City. He was later the host of Tic-Tac-Dough (replacing former host Wink Martindale) from 1985 until its cancellation the following year. He later hosted Top Card for TNN, The Nashville Network, for 2 seasons. Caldwell was born in Akron, Ohio. Since the early 1990s, he has hosted dozens of infomercials. However, arguably the best-known product for which his company produced and he hosted a series of infomercials was the RotoZip Spiral saw, a power tool that 'cuts holes, creates shapes, makes cut-outs' in virtually any construction material. It won 'Infomercial of the Year.' Caldwell's company Future Thunder Productions, Inc., (www.futurethunder.com) has been involved in writing, directing, or producing and certainly hosting over 120 infomercials. Classics include Dura-Lube, Dura-Shine, Flying Lure, Unbrakeable Autolock.
