 Yoga grew further with the help of television programmes and the arrival of major brands including Iyengar Yoga and Ashtanga Vinyasa Yoga.Before the 20th century, yoga was known only from the reports of travellers to India, which described deceptive vagabonds pretending to be pious.Among the first to publicise yoga in Britain in the early 1900s was the occultist Aleister Crowley, who confused yoga with magic in the public mind.
