The cost for a 30-second spot on TV's top programs

Ad Age recently published their  annual show-by-show guide  to the price of commercials, and live football continues to cost big bucks. NBC's "Sunday Night Football" came in first at $627,300 for a thirty-second spot and  CBS' "Thursday Night Football"  came in second at $483,333.

In terms of scripted shows, zombies take the cake. AMC's "The Walking Dead" is most expensive series, costing more than $400,000 for a package of spots. CBS' "The Big Bang Theory" is te most expensive broadcast entertainment program, averaging $344,827.

It's interesting how much can change in terms of pricing in just one year. CBS now has five of broadcast TV's 10 costliest shows. Fox actually had five last year, but not it only has one in the top 10 - "Sleepy Hollow."

The priciest spot on the CW is for "The Vampire Diaries" at $59,620. On ABC, the top spot is for critically-acclaimed comedy Modern Family at $239,650.

NBC's "State of Affairs" is a new series, but it still ranks eighth on the list, averaging $219,188 for a 30-second spot.

Ad Age's survey is compiled using data from as many as seven media-buying agencies. For more information on the study and how much it costs for a thirty-second spot on a variety of programs, click here.
