The WWE runs twelve pay-per-view events each year, typically at three to six week intervals. 2013 was no different, beginning with the Royal Rumble and the end of January and concluding with Tables, Ladders and Chairs (TLC) last Sunday. PPV's are meant to showcase the best matches of the year, given that many viewers are paying a premium to watch them. Many of this year's best encounters have taken place on free television, however, whilst some (such as Regal/Ohno and Zayn/Cesaro) have even taken place on NXT, the company's developmental show. As a result, several of this year's events have been lacking in places, though others have been excellent.
