Cura's business was at its peak in the mid-fifties, his business having doubled overnight following the launch of ITV in 1955. A second television set was purchased and a second camera constructed to enable Cura to photograph both channels. Cura also enjoyed success with two best-selling books on improving television reception and correcting picture faults, which were illustrated with his tele-snaps. He also appeared on the BBC's television panel game show "What's My Line?". Celebrity clients of the tele-snaps service included Benny Hill and the Beverley Sisters. By 1959, Cura claimed to have taken over 250,000 tele-snaps and that sets of his tele-snaps had been "presented to and graciously accepted by the Royal Family; Their Majesties the King of Denmark; the late King of Norway; Queen Juliana of the Netherlands; Ex-president Auriol of France; Earl Attlee; Sir Winston Churchill; Mr Charles Chaplin; Mrs Eleanor Roosevelt" as well as a wide range of newspapers and periodicals. However, when Cura raised the prices for his service in 1964, the BBC ordered a review of the tele-snap service, which at this stage was costing them £1,300 per annum, and, with many programmes now routinely recorded on film or video, the business began to decline.
