Melanie Griffith is on the phone to her agent right now, screeching at him to get that pitch for Working Girl 2 together (while gesturing to Antonio to get her another Stoli-and-Botox cocktail). Why? Because 80s nostalgia is in full swing, and mergers and acquisitions are back in style.

First up: GameStop is buying Electronics Boutique, creating a mega-chain of video game retailers. This isn’t necessarily as big a deal as it sounds, since the bulk of games these days are bought at big-box retailers like Target and Wal-Mart. Still, it’s a long way from when I was a kid and the only place in the neighborhood to buy (and try out) Atari 2600 carts was at the smoke-filled used computer store down the street from my middle school.

The big news, however, is Adobe’s acquisition of Macromedia. And I thought it was a big deal when they bought Aldus (PageMaker’s creator) so long ago. Just as that merger marked the end of a chapter in the history of desktop publishing (namely, the chapter where people still called it “desktop publishing”), this new deal has the potential to be a similar cultural marker — it’s not an event that will cause a shift in the way people think about online media production, but it is a representative absorption of online media into media in general. Web sites and Flash cartoons are no longer a novelty, they’re just the way things are done, just as doing layout on the computer instead of paste-up eventually became the normal way of working rather than some Greimanesque, cutting-edge technique. The Adobe/Macromedia merger can be read as signifying the way we’ve gotten used to living and working online.

Or maybe they’re just trying to hold Microsoft at bay. It’s always so hard to tell.
