Work and home audiences: BYOD
CNBC, the American business TV channel, does not want to use Nielsen measurements to guarantee its daytime audience. Why?
Because its audience cannot be accurately measured during this daypart. In the daytime, the network is watched mainly at the office (trading floors, etc.); since there are no people meters in offices, the work TV audience is not measured. The Nielsen people meter panel includes only households ("Nielsen families"). CNBC audiences in the evening (prime time) will still be guaranteed but for daytime TV, CNBC prefers to use its own "internal metrics" (cf. Sam Thielman, in Adweek).
Measuring audiences in the workplace can be a challenge for some media. It can be done for the press and radio: readership surveys or PPM (Portable People Meter, Arbitron / Nielsen) take all kinds of audiences into account, whatever their locations.
What about the Internet? Site-centric measurements cover audiences in the workplace. But what about panels (user-centric measurements)? Nielsen and comScore claim to measure Internet at work and they recruit people using computers at the office. What kind of company or IT department agrees to install measurement software to monitor company computers? Moreover, can we separate work from home use? This is probably an illusion: nowadays people carry their own laptop to the office; they work at home for their company; they use their company computer for personal tasks (e-commerce, mail, etc.); they bring company computers back home... That is why the majority of companies are implementing BYOD policies (cf. Bring Your Own Device): the consumerization of IT seems inevitable. BYOD is also said to be good for employee satisfaction and productivity... but includes security pitfalls (cf. "Avoiding BYOD desasters").
Audiences are not found only in the home. But while out-of-home audiences can be very important for TV and the Web, they are difficult to measure and, of course, to sell. Think of sports audiences: how many GRPs are going to be lost in out-of-home audiences, bars, hotels, offices, transportation?
