In the wake of studies showing that people prefer free to not-free (seriously, they needed studies?), ABC says it will offer its hit shows for free download with commercials, at its own Web site. If you simply can't abide the commercials, you can still buy the shows for $1.99 at iTunes (like always). Brilliant? Brilliant. Two points to ABC, assuming it doesn't muck it up with DRM and start firing off C&Ds when the shows end up on YouTube.
