Media Week - Capital Radio will step up its mobile telephone activity following a decision to retain its deal with mobile technology specialists Flytxt. The group will develop a cross-department strategy for its radio brands – Capital FM, Capital Gold Networks, Xfm, Choice FM and Century FM – to focus on sales, marketing and programming. A core part of the new strategy will be using Flytxt’s new strand of its Direct division, giving Capital’s in-house team the opportunity to develop SMS and MMS campaigns based around programming activities, such as quizzes and competitions.
