Advertising on television is generally expensive compared to say newspaper adverts but it can capture a wide captive audience if done at prime time. So if you have the money to spend in televised adverts, I'd say go for it. TV stations normally assist in developing content of the advert. So just visit your local TV station and get going.
You should make sure though that the prospective SFI Affiliates and/or TripleClicks PRMs are directed to you personally not just broadly to SFI and TripleClicks.
