A 2007 U.S. study by TNS Media Intelligence finds that spending on radio advertising dropped 3.5 percent from the previous year. Spending on Internet advertising surpassed radio advertising spending for the first time in 2007.

However a strong radio listening audience still remains, and the broadcasting industry is seeking to maintain that interest. Adapter requests on iPods are primarily for FM radio, suggesting that the listening device crowd still yearns for radio transmissions. Providing radio access on cell phones is also in consideration.

Likewise, Internet radio offers niche markets and access through Wi-Fi connections, while High Definition (HD) Radio expands the potential of traditional broadcasting signals (Tim Feran, "The Changing Face of Radio," The Columbus Dispatch, April 13, 2008).
