Does format change for screenplays/teleplays/etc?

Yes. Multicamera sitcom scripts have a different format than single-camera TV scrips, which have a slightly different format than film scripts.

The best way to understand the differences is to study scripts of the different formats. The johnaugust.com library has feature script samples, while this TV writing resource has examples of both multicamera and single-camera TV pilots, under US Comedies and US Dramas, respectively.
