For example, there were 720p tvs, 1080i tvs, only then 1080p came to the market. 1080i is considerably technically more difficult than 1080p, it isn't possible to make a 1080i tv that doesn't run 1080p internally. But the tvs were allowed to market in this order because 1080p looks the best and they hoped people will upgrade several times.
