In the 1970s very few boys' comics in the "slick" format were launched, although Polystyle's "Countdown" was one exception, launching in 1971 with content similar to "TV21" (which had disappeared by then) and "TV Comic". "Vulcan", a reprint title, was another, in 1976. Girls' titles which had launched in the slick format in the 1960s continued in that format into the 1970s; and others, such as "Diana" and "Judy", changed to become slicks. They found themselves in the same market as teenage titles for girls such as "Boyfriend" and "Blue Jeans", which had changed their content and were featuring mainly product-related articles and photo comics.
