In the first year, 400 beer houses opened and within eight years there were 46,000 across the country, far outnumbering the combined total of long-established taverns, pubs, inns and hotels. Because it was so easy to obtain permission and the profits could be huge compared to the low cost of gaining permission, the number of beer houses was continuing to rise and in some towns nearly every other house in a street could be a beer house. Finally in 1869 the growth had to be checked by magisterial control and new licensing laws were introduced. Only then was it made harder to get a licence, and the licensing laws which operate today were formulated.
