With the buzz surrounding Apple's launch of the ABC television episode sales on the iTunes Music Store, the other networks are stepping up their initiatives.
Mediapost reports that NBC and CBS are experimenting with online delivery of content.
CBS announced they will be distributing three episodes of prime-time sci-fi series "Threshold" online. Meanwhile, NBC is offering downloads of "NBC Nightly News with Brian Williams".
As expected, they report that CBS "has had talks with Apple about distributing CBS shows on iTunes." No other details are offered.
