In 1956, Victor Mills, the director of Development Department of P & G company, was looking after his newborn grandson when he deeply felt the troubles brought to housewives by baskets of dirty diapers. The responsibility of washing diapers inspired him. So Mills asked some of his most talented people to develop disposable diapers. The idea of disposable diapers is not new. In fact, there were several brands on the American market at that time. But market research shows that over the years, this diaper has accounted for only 1% of the U.S. market. The first reason is that the price is too high; Secondly, parents think that this kind of diaper is not easy to use. It is only suitable for traveling or when it is not convenient to change diapers normally. Research results show that the market potential of disposable diapers is huge. The United States and many countries around the world are in the post-war baby boom. Multiply the number of babies by the average number of diaper changes per day to get an astonishing potential sale. It took P & G product developers a year. The first sample was a pleated absorbent mat in a plastic underpants. But in the summer of 1958, the results of the field trial, except for the negative opinions of the parents and the rash on the baby, yielded nothing. In March 1959, P & G redesigned its disposable diapers, produced 37000 diapers in the laboratory and took them to New York State for field test. This time, two-thirds of the people who tried the product thought it was better than diapers. It is more difficult to reduce the cost and improve the quality of new products than to develop the products themselves. By December 1961, the project had entered the stage of production process and product trial sale which could pass the acceptance. The company chose Peoria, the most central city in the United States, to test sell the product, which was later named Pampers, and found that Peoria's mothers like to use "Pampers" but don't like the price of a 10 cent diaper. Trial sales in six places further show that a price of 6 cents a piece can make this kind of new product sell well. P & G has increased its production capacity to the level that enables it to sell baby diapers nationwide at that price. Pampers diaper was finally successfully launched, and it is still one of the top products of P & G today. (1) What is the basis of P & G's decision to develop disposable diapers? (2) At present, the market competition of diapers is becoming increasingly fierce. In order to maintain an advantage in the fierce market competition, what aspects of market research do you think P & G needs to carry out
