The internet wasn't as mainstream either...
Some still call the Internet a "phenomenon". Markets have evolved because of it, just as consumers' purchasing rhythms.
I wonder if color photography was still called a "phenomenon" in the 1970s, when it was by then a pretty established thing in daily life.
Pre-ordering wasn't invented as a marketing strategy: it
evolved from the observed behaviour of certain consumers who really (and I mean *really*) wanted something so bad, that in order to avoid the craziness of standing in line for hours (even days), or for waiting for a local store to come up with a physical item for weeks, or months (like was the case with the Wii in North America, for example). Smart people realized how cost-effective it was to supply to people who had already put the money down by saving some stock overhead.
Of course, nuances will get lost on others and those "others" can misuse the concept. Things aren't really that simple, and oversimplifying tend to begin their end.
Take those video games spinned-off movies, for example: big-wigs think that the brand itself will be enough to sell the video games, hence the little investment to creativity and detail...hence the poor sales. Sure, some will sell because there's always a hard-core fanbase, but it's just catering to the fanbase, not to videogame players as a whole.
Same thing with pre-sales: myopically seeing them as simply "a marketing tactic" by either the seller or the consumer just creates disappointment for both.
But, also, just because one doesn't understand it it doesn't mean it's a phenomenon. The OP does touch on that point: some see a money-maker, and since it's "new" (and, oh, how golden that word is in the marketing world), there's this big-wig/MBA pressure to adopt it (because, are you kidding me? you gotta do it, everybody's doing it!)
When companies learn to strike a balance between "maximizing" and "not-silver-bullet-izing", they succeed. Sometimes they find pet crack candies (like outsourcing, cost-cutting for the sake of cost-cutting, fad monetizing, etc.) and just can't quit it.
No, this is not a phenomenon, it's all very predictable: somebody finds something that works, and the copycats want in on the money shaker.
