Because the monkey could not be obtained without signing up to the service, a market for second-hand monkeys developed. At one time, original ITV Digital Monkeys were fetching several hundred pounds on eBay,[79] and knitting patterns delivered by email were sold for several pounds. The campaign was created by the advertising agency Mother.[80] In August 2002, following ITV Digital's collapse, Vegas claimed that he was owed money for the advertisements.[81] In early 2007, Monkey and Al reappeared in an advert for PG Tips tea, which at first included a reference to ITV Digital's downfall.
