What is the fine-grained topic of the following text: The professional market spurned Jessops for being too consumer oriented (with a limited in-store range and high prices) in favour of independent and online shops (or small, specialist chains like Calumet), and the bottom has fallen out of the consumer point-and-shoot market because almost everyone’s mobile phone has a half-decent point-and-shoot camera packaged in it. Only return the topic.
Decline of Jessops due to market preferences and rise of mobile photography.
