The plot thickens Now it's not enough to watch your favorite TV show -- you may soon have to pay to get the full story By Matthew Gilbert, Globe Staff | December 18, 2005 Madly in love with ''24," or ''Invasion," or ''Prison Break," or ''Family Guy"?

Extras such as commentary and deleted scenes have been with us for years on DVDs, and of course T-shirts and knickknacks are Marketing 101.
