"By your logic, people should be constantly bombarded with "important" stuff like price indices for medical services, world food prices, aggregate steel production, measures of industry concentration in the wholesale corn market etc." Never did I say anything about bombarding anyone or price indices. My logic is that media should give a more equal representation to major industry events like M&As, especially when two such events occur on the same day. I would not argue this if the acquired company was some Tubmlr sized biotech firm with a drug in trials, but this is a merger between two pharmaceutical manufacturers that outsize Tumblr in almost every statistic (users, revenue, employees, etc.) by 1-3 orders of magnitude. Oh and most people know nothing about pharma, just like they know little about what goes on in the background of their favorite sites in Silicon Valley, especially with acquisitions where integration takes a while and the public gets bored and forgets the event even happened.
