When EE launched 5G in the UK, they took out a full page ad with a massive headline saying simply "A real crowd pleaser"
One of the best adverts for a long time - if you knew about the technical advantages of 5G, it had a real double meaning.
If you knew 90s British dance music, it had a further humourous double meaning promoting the telco (an oblique reference to The Shamen's Ebenezer Goode)
