Forbes write that it is going slow in the US market.
After an initial burst of growth, mobile content–which can include everything from ring tones to video clips–is struggling to break out of the early adopter segment and achieve mass consumption. It is too soon to forecast the demise of this promising new field, but it is evident that wireless entertainment is wavering during a crucial transition to third-generation mobile telephony, or 3G.
According to Seattle-based mobile-market research firm M:Metrics, consumption of wireless content has flatlined. After eight quarters of rapid growth, sales in the two main categories, ring tones and mobile games, have stalled. Every month in the U.S., only 10% of mobile subscribers download a ring tone to their phones, and less than 4% download games. Text messaging is holding steady at about 33%.
