Each section of SRDS works differently. The Learn About links have short instructional videos. These will save you time in figuring these out!
EMU has an SRDS subscription for consumer magazines, websites, and tv and cable ad rates (see above). However, the sources below are also useful.
Note: Unfortunately, it is usually not possible to find published rates for TV ads. Your options are to:
1. estimate TV ad costs based on historical cost trend info
2. contact the TV channel to ask about rates
