Impractical Jokers never aired on Romedy Now. This show alongwith Big Bang Theory ( old initial seasons in both case) aired some years back on WB.
Well Content Acquisition by broadcasters work on a number of factors, Warner TV/ HBO content is quite popular here besides usual CBS, Fox, ABC shows. Now CBS runs channels like CW with Warner as partner in US and there r similar tie ups of broadcasters in production and channel front. All these and some other things have impact on how deals proceed in other countries.
Right now most of the Warner TV shows r going to Colors Infinity or Comedy Central bcoz CBS-Viacom now operate as one entity thus CBS is preferring its shows aired on CW to feature on Viacom chs here. Also Turner chs r distributed by Indiacast hence even Warner has warm relationship with Viacom18.
HBO ( Warner sister concern) has tie up with Star India for TV shows as same happened post exit of former's premium chs here in 2015. Star India as usual tries getting first rights over sister concern FX/Fox TV content and now Disney ABC shows like Supergirl, Gotham will move there.
CBS shows r scattered across bcoz of long term deals which have been going on since ages and likely to continue for sometime. NBC Universal again has presence on networks like AXN, Viacom 18 bcoz of the touch points shared by them on different levels, Sony has first output movie deal with Universal while NBC runs business news channel with TV18 as partner here.
Anyways as i have stated these r complex things. For each there r multitude of forces leading to final outcome
