While the majority of TV is pre-recorded or repeated content (think of all the repeats of the Simpsons, Real Housewives of X etc). We know whether a show is recorded or live and the broad categories that a given show falls into. We also break up our trending calculations into different groups based, News, Sports etc and treat the data differently (as seen in the apps)
Also, bear in mind that while a show might be prerecorded it still may show useful data. For instance The Colbert Report and The O' Reilly Factor are usually recorded shows, however they can talk about drastically different things from show to show, and even between segments in shows.
I grant that useful trends are more difficult to extract from sitcoms and other things like that, but just because a show isn't live, doesn't that no useful trending information can be extracted.
We look at trending data over various periods of time, from minute length to longer so we can gather sentence level, show level, series level and even channel level topics.
You might be able to use indexing to show potential bias. If you have access to the data, how often do the major news networks use the word "Obama" versus "President" over the course of the day? Say... Fox News, CNN, CNBC, MSNBC.
We actually had a very interesting page up for this in the run up to the 2012 election, comparing and graphing mentions of Obama and Romney on each network along with sentiment analysis of what they said about them.
The page has since been taken down but here are two of our blog posts about the analysis.
I have no tablet so cannot try. Is the data archived? Could I, say, go back and search for "topic X" that might have been in "newsmagazine program Y" in the past month?
