The Suite Life of Zack and Cody (2004-2008).
It was about two twins, the scheming teen operator Zack (Dylan) and the bookish intellectual Cody (Cole) who move into the posh Tipton Hotel, where their mother works as a singer. In an unprecedented 83 episodes, no one Said the Word, but gay subtexts were everywhere, from the gay-vague hotel manager Mr. Moseby to Zack's "date" with a popular boy to two boys obviously dancing together at a party.
They also left the world of acting behind. They enrolled in New York University, where Cole is studying archaeology, and is also an accomplished photographer. Dylan is studying video game design and fine arts, and sells his artwork online.
Both brothers are rumored to be gay, and Cole, the more feminine of the two, has been linked with Jake T. Austin, but they haven't made any public statements. Cole's tweets avoid any discussion of relationships. Dylan mentions men and women both, but states, in jest, that he's not attracted to either, just to cookies.
