Watch Presidential Campaign Ads Throughout History [VIDEO]

Many political observers have remarked that this election cycle is one of the most toxic in history, contending that campaign vitriol and inaccurate allegations have dominated the national discussion. But how does this campaign cycle compare to previous presidential election years?

For one, we are now inundated with campaign ads both on television and the web, from the official campaigns to PAC ads.

Thanks in part to the Museum of Moving Image, we can at least take look at campaign television ads throughout the decades since the first ads aired in 1952. Included in the collection are official campaign ads--so no devastating Swift Boat Veterans.
