 Promotional films of country music songs, however, continued to be produced.The Australian TV shows "Countdown" and "Sounds", both of which premiered in 1974, were significant in developing and popularizing what would later become the music video genre in Australia and other countries, and in establishing the importance of promotional film clips as a means of promoting both emerging acts and new releases by established acts.In early 1974, former radio DJ Graham Webb launched a weekly teen-oriented TV music show which screened on Sydney's ATN-7 on Saturday mornings; this was renamed "Sounds Unlimited" in 1975 and later shortened simply to "Sounds".
