There are many scrapers in NY titled with the names of large corporation like GM, Crysler, Exxon and IBM. Are these buildings really the headquarters? Do the companies really run their major business there?

  Well, nowadays rarely so, especially in case of such "physical" produce manufacturers as the abovementioned. As far as I know, corps such as Chrysler or IBM have never had their main HQ in the city, despite showy buildings (and the IBM relocated altogether from the namesake building in the early 1990s).
  Companies offering the "creative" services, such as publishing or broadcasting, have stuck to the city more loyally. For example, although the GE Building has little General Electric "hardware" consortium activities within, the NBC broadcasting company (which GE bought from the original owner of the building, RCA) still has its headquarters and studios there, in the "Radio City". Similarly, banks and investment houses seem to have remained and, despite changing names and hands continuously ;^), in some cases still occupy the namesake building with the HQ bureaux (Chase and the World Financial Center towers (?)).
  In many cases the company which first co-developed the namesake building has left it altogether. In some cases the original name remains (Woolworth Building), in some the new owner changes it after the transaction (Sony Building) -- this also leads to dilemmas on how to name the buildings in this study. For this reason, some of the buildings have thus, for example, several names listed on the alphabetical entry list.
  One of the decisive reasons for the relocation to the greener pastures (across Hudson River or farther into the US) has been the more lucrative taxation of the corporations there -- although in pressing situations, such as the threat of the NY Stock Exchange stepping out to New Jersey, the city administration has offered tax abatements...
  And, oh yes, the Trump activities are headquartered from the Trump Tower... ;^) ED
