Text messaging has been particularly effective in keeping certain audiences engaged recently, with television show voting and information requests being solicited from customers using SMS. Clear Channel wants to join in the fun, as the terrestrial radio company wants listeners to all its stations nationwide to use texting to send in song requests. In addition to requests, listeners can get traffic reports along with other relevant information tidbits. With a failed trial having just been completed with AT&T where a fee was involved, the company will instead be focusing on a free model that relies heavily on text messaging. This new program will start in New York City and will expand to 100 radio stations by the end of 2008. We kinda hope Clear Channel really does not wait over 18 months to make this available to many large markets. Hear us, CC?
