What the media chooses to cover (and what consumers choose to read, since we no longer have the limited-sources excuse) has pretty much nothing to do with the actual big-picture importance of the events.
They do not care about health (America is the fattest, unhealthiest country on the planet), they don't care about science & technology (Tumblr, IG, FB, reality TV, TMZ, etc. dominate the news/app/entertainment spectrum and bring little to no value), they care about GIFs, cats, Kim Kardashian and other brain dead agenda.
It's very unfortunate but that's the way it is. People could care less about Warner Chilcott. They care about stupidity.
Companies like IG, Tumblr, and others are smart because they seem to employ the "if you can't beat em, join 'em" logic.
Couldn't. "People couldn't care less ..."
English -- any natural language that's progressed beyond early creole, for that matter -- is not, and should not be treated like, a completely self-consistent system of formal logic. "Me" (or other "object" pronouns) in a compound subject is correct, as are double negatives, split infinitives (English doesn't actually have an infinitive, it has a form of phrase that occupies the function of one), and so forth. The prescriptivist dictates of Lowth, Murray and Cobbett are an artificial imposition on language that rejects them at every turn. It's time to use the real grammar of the language, rather than trying to structure English on some formal (and, it would seem, rarely spoken) version of Latin or Greek.
I don't know whether this type of industry can be called mature, but it was the fastest growing sector of the economy in the US for this year, if I'm not mistaken. A quick google search yields e.g. http://www.smartplanet.com/blog/smart-takes/top-10-fastest-g...
On the question of whether it will shake things up, there sure is some turmoil. Watson/Actavis has been on buying spree for like 2 years now. Besides minor players here and there (e.g. Specifar in Greece), they acquired the Actavis group and now they acquired Warner Chilcott. They were (I think) 5th and in a relatively small period they ended up being the 3rd largest generic drug company worldwide.
I have the impression that the blogging market is actually kind of over-saturated.
a) Yahoo
b) Mayer
Tumblr is a non issue in the size of the story other than the "high school dropout makes big". Yahoo and Mayer have been trending for awhile. There is probably not so little of "omg what in the hell are they thinking with that price" going on too.
