Changes in ISIC, Rev.4 291 ing activities (division 58), including software publishing; motion picture and sound recording activities (division 59); radio and TV broadcasting and programming activi- ties (division 60); telecommunications activities (division 61); information technology activities (division 62); and other information service activities (division 63). These activities had been included in ISIC, Rev.3.1 sections D (Manufacturing), I (Transport, storage and communications), K (Real estate, renting and business activities) and O (Other community, social and personal service activities), therefore strongly impact- ing comparability with the previous ISIC version. However, this new treatment of information and communication activities provides a more consistent approach that is based on the character of the activities carried out. 256. In section K (Finance and insurance activities), two classes have been introduced that go beyond the traditional scope of ISIC in covering economic pro- duction; classes 6420 (Activities of holding companies) and 6430 (Trusts, funds and similar financial entities). 257. The ISIC, Rev.3.1 section entitled “Real estate, renting and business activi- ties” has been split up into three sections in ISIC, Rev.4. Real estate is now represented as a stand-alone section (section L) due to its size and importance in the System of National Accounts. The remaining activities have been separated into a section M (Professional, scientific and technical activities), covering activities that require a high degree of training and make specialized knowledge and skills available to users; and a section N (Administrative and support service activities), covering activities that support general business operations and do not focus on the transfer of specialized knowledge. Computer and related activities (ISIC, Rev.3.1 division 72) are no longer included in this section. Computer repair activities have been grouped with repair of household goods in section S, while software publishing and IT activities have been grouped in the new section J. 258. The scope of education (section P) has been changed to explicitly include specialized sports, cultural and other education, and also to include specialized sup- port services. 259. More detail has been created under section Q (Human health and social work activities), resulting in the creation of three divisions instead of one, as in the previous version of ISIC. In addition, the focus has been narrowed to include only “human health” activities, providing a better tool for measuring this important part of the economy. As a result, veterinary activities have been removed from this section and placed as a division in section M (Professional, scientific and technical activities). 260. Substantial components of ISIC, Rev.3.1 section O (Other community, social and personal service activities) have been moved to ISIC, Rev.4 sections E (Water supply; sewerage, waste management and remediation activities) and J (Infor- mation and communication), as described above. The remaining activities have been regrouped into new sections R (Arts, entertainment and recreation) and S (Other serv- ice activities). As a result, such activities as creative arts, library activities and gambling activities have been raised to the division level. The repair of computers and personal and household goods (ISIC, Rev. 3.1 classes 5260 and 7250) is now included in this new section S.
