Apple could surprise iPad buyers by halving the price of TV shows on iTunes by the time the tablet is in stores, a leak hinted Wednesday night. A number of unnamed studios have supposedly agreed to repeated calls from Apple to cut the price per episode to $1 in a "test" that would gauge interest in lower-priced standard definition shows. The drop would hopefully result in disproportionately higher sales by attracting those otherwise scared off by the normal $2 price tag.
