to establish the "Playing What We Want" concept which was new to Toronto. DJs were introduced within weeks. In November 2005, Cardinal defended his decision in an interview with Michael Hainsworth of Report on Business Television and stated why he doesn't see commercial-free iPods and satellite radio as a threat to a non-DJ format. In October 2005, Entravision Radio launched a Spanish-language version of the Jack format dubbed "José" with the "We Play What We Want" tagline translated into Spanish as "Toca lo que Quiere". "José" went live on six FM and AM stations in Sacramento, Stockton, and Modesto, California; Albuquerque, New Mexico; and Denver, Colorado. The "José" stations have no affiliation with Jack, SparkNet Communications, or Bob Perry. On October 25, 2005, Infinity Broadcasting, part of CBS, announced that it would be replacing Howard Stern with Jack FM on some of its stations.

However, in many cities the novelty wore off, and in the late 2000s a number of Jack stations modified their playlists drastically or flipped to other formats outright.

In 2010, the tagline was changed again to "Regina's Greatest Hits". In October 2006, the UK's first Jack FM format station won a broadcast licence for the Oxford area. 106 Jack FM Oxford started broadcasting at 1:06 PM BST on October 18, 2007. On December 2, 2009, Bristol radio station Original FM changed to Jack FM after requesting a format change with OFCOM. Two further Jack FM stations were planned
