"TM Studios, Inc." is a radio jingle and promotional music service company based in Dallas, Texas (USA). It is currently the oldest radio jingle company still in business, with roots tracing back to 1955 when Tom Merriman (the original "TM" in TM Studios) founded Commercial Recording Corporation (which closed in 1968). Tom Merriman left CRC in 1967 and founded TM Productions (later known as TM Communications, Inc. - a publicly traded company) with Jim Long. By this time, Century 21 Productions (later known as Century 21 Programming, Inc.), another Dallas jingle company, was founded.
