As Senseio Publishing executive director Wu Ching-chuan points out, although there was a potential market of 300,000 textbooks in the first year, once it was split among the five or six biggest publishers, any individual firm could only sell 50-60,000 books at best. "Although we've already invested a certain amount in the market, we're still uncertain how much room for development remains," says Wu.
新學友出版公司執行長吳清全指出，以第一年來說，三十餘萬市場給比較大的五、六家廠商分，每家僅得五、六萬，「已投入的部份不說，我們還在考慮將來教科書的發展性有多少？」
