2022 Economic Census / NAICS 51621

Media streaming distribution services, social networks, and other media networks and content providers

The four largest firms in Media streaming distribution services, social networks, and other media networks and content providers accounted for 41.2% of the industry's 2022 sales, value of shipments, or revenue, and its concentration (HHI 638) ranks 93 of 465 NAICS industries in the Economic Census. What is HHI?

National employer-firm concentration for this naics industry, measured from sales, value of shipments, or revenue. Census categories are statistical groupings, not necessarily antitrust markets.

Five-year deltas are published only for rows whose NAICS code and industry label are identical in the 2017 and 2022 Census tables. This strict match is a conservative screening rule, not an official NAICS concordance or evidence of causation. Revenue changes are nominal and are not adjusted for inflation.

Every formation and business-dynamics reading in this chapter describes the broader Information sector (NAICS 51), not Media streaming distribution services, social networks, and other media networks and content providers (NAICS 51621) by itself. This atlas joins only exact broad-sector NAICS contracts across three separate Census systems: monthly Business Formation Statistics, annual Business Dynamics Statistics, and Economic Census industry structure. The release clocks, populations, denominators, and measures remain distinct. Positions are descriptive context, not composite competition scores, causal estimates, legal antitrust markets, or evidence that applications, entry, concentration, and competitive effects are interchangeable.

Parent-group boundary

Every JOLTS and CES reading in this chapter describes the broader Information and Information BLS groups mapped through parent sector NAICS 51, not Media streaming distribution services, social networks, and other media networks and content providers (NAICS 51621) by itself. JOLTS industry rates describe national labor demand and worker-flow activity in broad BLS industry groups. They do not measure employer concentration, monopsony power, wages, bargaining power, job quality, local labor-market conditions, worker substitutability, a legal labor market, or the competitive cause of a change. The job openings rate uses employment plus openings as its denominator. Hires, quits, and layoffs and discharges use employment. Rates may be compared across published industry groups within the same measure, but different measures must not be added together or treated as a common flow balance. CES employment, hours, and earnings describe national payroll jobs and establishment averages in broad private-industry groups. They do not measure unique workers, vacancies, employer concentration, monopsony power, bargaining power, job quality, a local or occupational labor market, a legal antitrust market, or the competitive cause of a change. All-employee hourly earnings are current-dollar averages and are not adjusted for inflation. Changes can reflect shifts in industry and worker composition. Employment is reported in thousands of payroll jobs, so multiple jobholders may be counted more than once. Compare industries only within the same published measure; do not add or ratio the three measures into a common score. The two releases remain separate and are not combined into a labor-market, monopsony, competition, welfare, or causal score.

Parent-sector boundary

Every BEA reading in this chapter describes parent sector Information (NAICS 51), not Media streaming distribution services, social networks, and other media networks and content providers (NAICS 51621) by itself. No value is allocated to the narrower industry. BEA value added measures an industry's contribution to GDP. It is not sales, gross output, profit, a markup, market share, concentration, a legal antitrust market, or evidence of competitive harm or causation. Current-dollar value-added shares reflect both prices and quantities. Real value added uses chained 2017 dollars and is suitable for growth comparisons, but chained-dollar industry components are not additive. Quarterly levels are seasonally adjusted at annual rates, and quarterly growth and contribution measures retain BEA's published annualized convention. The BEA table contains nested industries, cross-industry aggregates, and addenda. Only the 20 major-industry rows form the composition view; summing those rows with their children, parent aggregates, or addenda would double count activity.

Directory boundary

This chapter is a directory of 4 BEA summary industries classified inside parent sector Information (NAICS 51). No coefficient is averaged, summed across buyer columns, or allocated to Media streaming distribution services, social networks, and other media networks and content providers (NAICS 51621). A domestic total-requirements coefficient reports the U.S. output required from the supplier-row industry, directly and indirectly, per dollar of output delivered to final use by the buyer-column industry. It is not observed spending, a contract, a firm supplier link, market share, concentration, a legal antitrust market, competitive harm, or causation. Rows are supplying industries and columns are buyer industries delivering output to final use. Reading down a buyer column traces upstream requirements; reading across a supplier row traces the industries whose final-use output requires that supplier. BEA requirements tables use fixed input structures, constant returns to scale, and no input substitution. Coefficients are average, ex-post industry relationships; domestic import adjustments are estimated and do not identify firm-specific sourcing. Diagonal values include an industry's own direct and indirect requirements. Published negative coefficients are retained as accounting adjustments and must not be ranked as positive supply requirements.

Industry screen, not market conclusion

A NAICS industry is a statistical classification, not a legally defined antitrust market. Use these national revenue concentration measures to screen where deeper product and geographic market analysis may be warranted, not to infer market power or liability.
