Disney announced on Monday that ABC.com’s trial run of free TV episodes streamed online has been a success.  The episodes included 30-second advertisements, and, apparently, an online exit survey from the first week of the trial showed that 87 percent of respondents could remember the products advertised in the ads.  Execs are so pleased that a reworked version of the current site will appear in the Fall.  In fact, not only did the free episodes outperform the $1.99 ABC episodes offered on iTunes, but actual televsion viewership increased rather than decreased during the trial period.  The trial run will still end on June 30 as originally planned.  As much as I like the iTunes model, I can see why this is working.  Like my mom says, “If it’s free, it’s for me!”
