most audience research relied upon were based on a fairly uniform nationwide availability of technologies and programming, and thus reflected a network-era experience with television. The arrival of varied programming tiers of cable channels challenged the system as US television homes began having highly descriptive access to technology and programming and consequently began using television in significantly different ways. Although the A/P meter solved the problem of DVR use, programming on video on demand systems did not include the "audio watermark" used by the device. The nation's many cable providers also limited access to the proprietary data recorded by their set top boxes, which reduced the informational gain offered by this technology. Video on demand desperately needed to establish measurement matrices to prove its economic viability, but the lack of shared and consistent information further confounded knowledge about use. Likewise, the erosion of the thirty- second advertisement's dominance and the new advertising strategies that became increasingly common required the creation of new methods and matrices to determine value and pricing. The goal of these leading providers in automated audience measurement solutions is to deliver results to inquiries such as: The nature of the audience, the number of viewers, the content viewed, the amount of time spent on viewing, the type of display utilized and the audience interest in those displays. In "The Television Will be Revolutionized", Amanda Lotz clearly indicates how technological development in the audience measurement practice provides a multitude of technological advancements such as the DVR, Video-On-Demand portable devices such as the iPod and even a boost in mobile phone proficiencies. These improvements comply with television viewing not to be restrained to be "home-watched". Internet measurement is taken to the next level through its sophistication and high tech distribution. This allows several audiences measurement companies to refer to the Internet as the most measurable media. Demographics The demographic of a particular show's audience is also measured. This is often notated in an abbreviated form, e.g.: P2+ = Persons aged 2 or more P12–34 = Persons aged 12 to 34 P18–49 = Persons aged 18 to 49 A18–34 = Adults aged 18 to 34 Men 18–34 Women 18–34 Ratings point Ratings point is a measure of viewership of a particular television programme. One single television ratings point (Rtg or TVR) represents 1% of television households in the surveyed area in a given minute. As of 2004, there are an
