FOX soccer channel/BEin Sports, ESPN, etc pretty much did in Summers.[...]
That, plus Arlington's legendary overdevelopment...still approving new office blocks despite a 30% office vacancy rate in Rosslyn and probably a similar level in DOD-abandoned Crystal City, and approving new flats/condos despite ongoing vacancies in Columbia Pike and elsewhere (probably because they're unaffordable to so many). In fact they tried to kick Summers out of its current site back round 2003...the county board's M.O. seems to be, why have a (then-)popular independent business when you can have a big ugly office/condo block and chain stores on the same site and hopefully collect more in property taxes to fund projects like Artisphere and the Columbia Pike streetcar? (Read some of the comments on the article I linked earlier for more insights.)
