Advertisers will have to cough up $1 million for a 30-second ad on the swan song of Oprah Winfrey’s syndicated talk show -- this according to Brad Adgate, research SVP of Horizon Media.

That’s more expensive than when ABC’s “Lost” mercifully came to an end last May -- a 30-second spot for the intensely weird drama’s ending cost $900,000. However, CBS’s family comedy “Everybody Loves Raymond” raked in $1.2 million for each 30-second ad in 2005.

And before you wonder how Ray Romano commanded so many ad dollars, consider that the 1998 “Seinfeld” finale 30-second spot ran for $1.4 million, and the “Friends” series end in 2004 bested everyone, costing $2 million per 30-second ad, WaPo TeamTV’s Emily Yahr reports.

Oh, and also the fact that “The Oprah Winfrey Show” is a daytime series, which makes the comparison with the above primetime shows all the more impressive.

The finale of Oprah’s show -- details of which are being kept a closely guarded secret -- airs Wednesday, May 25.
