TV Essentials ... what's the story?
What is going on with TV Essentials? I was talking to a friend of mine who works as a media planner at a big media buying firm on Madison Avenue and she said she's never heard of Rentrak. She says there are only three companies out there selling their wares and she said its Nielsen Media Research, TNS and Erinmedia.
How is Rentrak different? Do they own patents? I searched on Google patents and found only patent 5396417 issued in March of 2005, but it doesn't seem to have anything to do with television. Nielsen Media Research has literally, hundreds of patents. If you search Taylor Nelson Sofres you get zip. Erinmedia has four patents but they all appear to be about cable box data and television.
Does anyone have any insight here?
