State of the Computer Book Market - Mid-Year 2009

If you have read previous State of the Computer Book Market posts, you know we typically publish between 3-5 posts that summarize the computer book market for a given year. SInce it's mid-year, I thought I'd do a shorter, one-post summary of where things stand in 2009 thus far. The picture looks like our US economy: lots of bad news peppered with small glimmers of hope. So let's look at the Market, Categories, Publishers, and Languages.

The market has been on a steady decline since mid-2008 and has continued downward right through the first half of 2009. And there are very few signs that the book-buying slump is going to turn around anytime soon. Overall, the market saw 595,821 fewer units sold in the first half of 2009 than were sold in the same period of 2008. Although we do not have data to show the trends between 2000 and 2003, the market performance this year is the worst we've seen since the fall of of 2001. You'll notice in the chart below that the seasonal patterns have remained consistent, but sales are at a much lower volume than any previous year.

State of the Computer Book Market 2008, part 4 -- The Languages

In this fourth post (parts one, two and three are found here) on the State of the Computer Book Market, we will look at programming languages and drill in a little on each language area.

Overall the market for programming languages was down 5.9% in 2008 when compared with 2007. There were 1,849,974 units sold in 2007 versus 1,740,808 units sold in 2008, which is a decrease of 109,166  units. So the unhealthy 8% loss in the Overall Computer Book Market was not completely fueled by programming-oriented books.

State of the Computer Book Market, Part 4 - The Languages

Note: An inadvertent draft of this post went out in our RSS feed and was posted for about an hour on Tuesday. It was cloned from Q1 '07 and most of the data and information was wrong.

In this fourth post (one, two and three are found here) on the State of the Computer Book Market, we will look at programming languages and drill in a little on each language area.

Overall the 2007 market for programming languages was down (1.67%) in 2007 when compared with 2006. There were 1,809,695 units sold in 2006 versus 1,779,523 units sold in 2007 which is (30,172) fewer units in 2007. So the modest 1% growth in the Overall Computer Book Market must have been fueled by non-programming oriented books. You don't need a programming language to learn to use MacOsX, Vista or Office and that is where the growth was in 2007.

State of the Computer Book Market, Part 2: The Technologies

In this second installment (the first post is found here), we look at computer book sales in specific technology categories. Remember that we've organized the data into six "Category Families" -- Systems and Programming, Web Design and Development, Business Applications, Digital Media Applications, Consumer Operating Systems and Devices, and Other. Within each Family are category group, super-category, category, and atomic category, in a five-level hierarchy. For example, Systems and Programming includes programming languages, databases, software engineering, general programming, security, and so on. In the rest of this post, we will contrast Q4 2006 with Q4 2007 and the whole year of 2006 with 2007.

As a refresher, here is a new view of the Category Families with their sub areas for Q4 2007 compared to Q4 2006. In this view, we've changed the thickness of the borders to highlight the category hierarchy.

Recapping the big picture from the last post, what you didn't see is that the fast growth of Windows Vista was aided by the addition of 63 new titles [title count] that made the Bookscan data-set in 2007. (The data set consists of the top 10,000 computer books. So more titles in a given category typically means that new titles in that category have pushed titles from other categories off the bottom of the list. Shrinkage in the title count in a category doesn't necessarily mean that titles are unavailable, just that they are no longer selling enough copies to make the list.)

There were 15 Vista titles in the 2006 data and on 12/31/07 there were 78 or an 420% increase in count, while XP declined at a slower rate going from 125 titles in 2006 to 97 in 2007 for a -22.4% decrease in count. Combined, that netted 35 more titles in 2007 than in 2006 for XP and Vista. This is a distinct (isbn) count as well, so if a title makes it in the top 10,000 report for more than one week, it is counted only once. We wanted to see how many titles made up the category, not how often a title makes the report. But there is more to this category than is visibly apparent and we will cover that in more detail later in this post.

In the table immediately below, you can see how the cat_family groupings have performed (total units) both by quarter and yearly results. The only noticeable change is that the Consumer Operating Systems has swapped positions with Digital Media at the number 4 & 5 ranks.
