A 2-man tent is great for sleeping in, but not much else! You need a Packa Shack to give you somewhere to sit, get changed, wash, cook and whatever else you want to get up to in the great outdoors!
But where does this great activity come from, in terms of recreational camping, well let me pass on some info from Wikipedia...
The history of recreational camping is often traced back to Thomas Hiram Holding, a British travelling tailor, but it was actually first popularised in the UK on the river Thames. By the 1880s large numbers of visitors took part in the pastime, which was connected to the late Victorian craze for pleasure boating. The early camping equipment was very heavy, so it was convenient to transport it by boat or to use craft that converted into tents. Although Thomas Hiram Holding is often seen as the father of modern camping in the UK, he was responsible for popularising a different type of camping in the early twentieth century. He experienced the activity in the wild from his youth, when he had spent much time with his parents traveling across the American prairies. Later he embarked on a cycling and camping tour with some friends across Ireland. His book on his Ireland experience, Cycle and Camp in Connemara led to the formation of the first camping group in 1901, the Association of Cycle Campers, later to become the Camping and Caravanning Club. He wrote The Campers Handbook in 1908, so that he could share his enthusiasm for the great outdoors with the world.
Possibly the first commercial camping ground in the world was Cunningham’s camp, near Douglas, Isle of Man, which opened in 1894. In 1906 the Association of Cycle Campers opened its first own camping site, in Weybridge. By that time the organization had several hundred members. In 1910 the Association was merged into the National Camping Club. Although WW1 was responsible for a certain hiatus in camping activity, the association received a new lease of life after the war when Sir Robert Baden-Powell (founder of the Boy Scouts movement) became its president.
