Two former auction channels both owned by parent company SitUp TV Limited, which originally broadcast on the Digital Terrestrial platform on channels 23 and 24 respectively. Bidup.tv launched first, being a traditional auction channel, where an item started at a certain value, then folks would bid up until a final price was reached. A successful formula, or at least so it seemed until Pricedrop came along. Pricedrop worked in reverse. The price started off high, and fell down to its final price. This latter formula proved more popular and wiithin a short space of time the traditional auctions on BidUp.tv vanished in favour of the exact same 'falling-price' style auctions, hence the renaming of it to bid.tv (Removing the up, as prices no longer went...um... up!).
The channels were renamed one more time, before the parent company went into administration in 2014. In more recent times the brands of the former channels have been purchased and a relaunch promised, although it bears no connection to the original company.
