I'm not sure what you were looking for as a reply...but at least I will address the examples you gave.
Out of the thousands of stores (I'm not talking about just mega-conglomerates) in NYC, you found 5 that went out of biz...which we've all heard before...but I will recount them for ya
1)FAO Schwarz had been hurting for years...ever since their failure in the early 2000s to adopt online customers while Amazon and Toys.com killed them in sales...not to mention it was literally an hour+ wait just to get in the store every single day...FAOS was, for a long time, more of a "let's go in, pay the $10 to ride the store train, and tell mom and dad we went there!"...it was a place to tell someone "you went there" like going to the Statue of Liberty or Niagara Falls.
2)Tower Records...come one, that ENTIRE CHAIN fell apart in 2001 due to Amazon, iTunes, CD Universe, eBay, CDNow, and the billion other online stores...not to mention the ability to see and buy 100 times the selection of "imports" on the net...I've been buying cds online since 1997 or earlier...routinely...I'm an ex-dj.
3)Lord & Taylor...no specific comment since I never go there...but they've been doing bad all over, too, as my wife tells me.
4)Starbucks...sheeez...that chain fell apart about 4 years ago...when the bubble burst in early 2002, nobody had money to go buy their $5 coffees anymore. They've been closing places all over the country for years...didn't you see the headlines a few years ago that they were closing like 40% of their locations?
5)Gateyway...come on...are you serious? There are like 4 GW stores in the country...the last time I even SAW one was 10 years ago in Natick, MA. You might as well have told me Fred's Air Conditiong Shop closed down.
