Yet another business so deeply invested in an outdated paradigm it couldn't reinvent itself. Imagine if they'd taken a hint from Napster or Amazon early on.
Even at their peak of profitability Columbia House seemed like such an anachronism I couldn't figure out why anyone bought from them. Too often businesses like that resorted to sneaky, predatory "value added" crap crammed onto bills that went unnoticed for months.
If I had to guess, I'd bet their main customers were folks like my grandparents who lived much longer than earlier generations, with plenty of disposable income but limited mobility. They were just old enough to fondly remember the old mail order businesses like Sears, Wards, Burpee gardening catalogs, etc., and young enough to appreciate the burgeoning TV home shopping networks. I've had to wean my mom away from mail order catalogs like Haband, which operate in a marginally shady way, selling good quality items at reasonable prices, but cramming despicable predatory profit-building schemes into the orders of unwary older folks, such as "added value" coupon booklets of dubious value. Those shady practices only serve to kill off the few remaining old school mail order and TV order businesses.
As that generation of shoppers died, so did the customer base for outdated businesses like Columbia House, Blockbuster, etc.
For the most part, good riddance. Dead weight businesses that couldn't or wouldn't adapt, and too often resorted to sneaky, predatory practices to compensate for profits lost to discounted prices.
