Not a trick, and you were right but for the wrong reason.
The BBC demonstrated a prototype Ceefax on Tomorrow's World in October 1972, and it was in field trials in 1973. The Internet was invented in 1973, and Stanford, BBN, UCL, et al. were pushing packets around by 1975.
New pence, Ceefax, ABBA, and (according to its inventor) the pronoun "xe" all pre-date the Internet.
