The 1968 competition's final tournament format expanded to include eight of the 22 teams entered in the preliminary rounds. The qualifying teams were distributed in two groups of four to play single round-robin tournaments, with the top two teams of each group advancing to semi-finals, a system that remained in use for the finals until 1992. The Democratic Republic of Congo won its first title, beating Ghana in the final. Starting with the 1968 tournament, the competition was regularly held every two years in even-numbered years; this ended with the 2012 tournament, which was followed by a tournament in 2013, and successor editions in each odd-numbered year. Ivory Coast forward Laurent Pokou led the 1968 and 1970 tournaments in scoring, with six and eight goals respectively, and his total of 14 goals remained the all-time record until 2008. Play was covered for television for the first time during the 1970 tournament in Sudan, as the hosts lifted the trophy after defeating Ghana—who were playing their fourth consecutive final.
