Another challenge to the industry was consumers' turning to digital cable, the internet and devices other than their television sets to view entertainment content. As new ways of measurement were becoming readily available and people could easily be tracked and monitored for content and use, the industry worried that traditional sampling techniques might become obsolete. Furthermore, the increasing fragmentation of viewing across different technologies posed difficulties in reporting actual viewer numbers for a content piece. In 2010 Nielsen began rolling out its "anytime anywhere media measurement" initiative, which includes DVR views in the television figures. Dubbed “GTAM,” which stands for Global Television Audience Metering, is based on the development of new audience metering technologies aimed at dealing with all of the conceivable challenges involved in measuring the video viewing behavior of contemporary consumer households across multiple platforms (TV, Internet, mobile devices). Existing A/P meters will be replaced by so-called GTAM meters which are expected to utilize a combination of active and passive measurement technologies. However, unlike A/P meters, they will not require a physical connection to any media devices to function.
