In the 1990s, audience research methods generally were thrown into question with the arrival of new media, especially digital media and changes to the public's media habits. People meters, which recorded the household's viewing by noting the station to which a TV was tuned, failed to capture new viewing habits such as recording programs for playback at a later time or watching a podcast / download on another device such as a tablet or computer. The proliferation of new media has given consumers much greater control over where and when they access content. For instance, Video on Demand (VoD) enables consumers to decide "when" to watch programs while smartphones enable consumers to decide "where" to access content. Media research companies have been forced to devise new methodologies capable of tracking new and unprecedented viewing habits across a diverse range of different platforms.
